+### GNU GENERAL PUBLIC LICENSE
+
+Version 3, 29 June 2007
+
+Copyright (C) 2007 Free Software Foundation, Inc.
+<http://fsf.org/>
+
+Everyone is permitted to copy and distribute verbatim copies of this
+license document, but changing it is not allowed.
+
+### Preamble
+
+The GNU General Public License is a free, copyleft license for
+software and other kinds of works.
+
+The licenses for most software and other practical works are designed
+to take away your freedom to share and change the works. By contrast,
+the GNU General Public License is intended to guarantee your freedom
+to share and change all versions of a program--to make sure it remains
+free software for all its users. We, the Free Software Foundation, use
+the GNU General Public License for most of our software; it applies
+also to any other work released this way by its authors. You can apply
+it to your programs, too.
+
+When we speak of free software, we are referring to freedom, not
+price. Our General Public Licenses are designed to make sure that you
+have the freedom to distribute copies of free software (and charge for
+them if you wish), that you receive source code or can get it if you
+want it, that you can change the software or use pieces of it in new
+free programs, and that you know you can do these things.
+
+To protect your rights, we need to prevent others from denying you
+these rights or asking you to surrender the rights. Therefore, you
+have certain responsibilities if you distribute copies of the
+software, or if you modify it: responsibilities to respect the freedom
+of others.
+
+For example, if you distribute copies of such a program, whether
+gratis or for a fee, you must pass on to the recipients the same
+freedoms that you received. You must make sure that they, too, receive
+or can get the source code. And you must show them these terms so they
+know their rights.
+
+Developers that use the GNU GPL protect your rights with two steps:
+(1) assert copyright on the software, and (2) offer you this License
+giving you legal permission to copy, distribute and/or modify it.
+
+For the developers' and authors' protection, the GPL clearly explains
+that there is no warranty for this free software. For both users' and
+authors' sake, the GPL requires that modified versions be marked as
+changed, so that their problems will not be attributed erroneously to
+authors of previous versions.
+
+Some devices are designed to deny users access to install or run
+modified versions of the software inside them, although the
+manufacturer can do so. This is fundamentally incompatible with the
+aim of protecting users' freedom to change the software. The
+systematic pattern of such abuse occurs in the area of products for
+individuals to use, which is precisely where it is most unacceptable.
+Therefore, we have designed this version of the GPL to prohibit the
+practice for those products. If such problems arise substantially in
+other domains, we stand ready to extend this provision to those
+domains in future versions of the GPL, as needed to protect the
+freedom of users.
+
+Finally, every program is threatened constantly by software patents.
+States should not allow patents to restrict development and use of
+software on general-purpose computers, but in those that do, we wish
+to avoid the special danger that patents applied to a free program
+could make it effectively proprietary. To prevent this, the GPL
+assures that patents cannot be used to render the program non-free.
+
+The precise terms and conditions for copying, distribution and
+modification follow.
+
+### TERMS AND CONDITIONS
+
+#### 0. Definitions.
+
+"This License" refers to version 3 of the GNU General Public License.
+
+"Copyright" also means copyright-like laws that apply to other kinds
+of works, such as semiconductor masks.
+
+"The Program" refers to any copyrightable work licensed under this
+License. Each licensee is addressed as "you". "Licensees" and
+"recipients" may be individuals or organizations.
+
+To "modify" a work means to copy from or adapt all or part of the work
+in a fashion requiring copyright permission, other than the making of
+an exact copy. The resulting work is called a "modified version" of
+the earlier work or a work "based on" the earlier work.
+
+A "covered work" means either the unmodified Program or a work based
+on the Program.
+
+To "propagate" a work means to do anything with it that, without
+permission, would make you directly or secondarily liable for
+infringement under applicable copyright law, except executing it on a
+computer or modifying a private copy. Propagation includes copying,
+distribution (with or without modification), making available to the
+public, and in some countries other activities as well.
+
+To "convey" a work means any kind of propagation that enables other
+parties to make or receive copies. Mere interaction with a user
+through a computer network, with no transfer of a copy, is not
+conveying.
+
+An interactive user interface displays "Appropriate Legal Notices" to
+the extent that it includes a convenient and prominently visible
+feature that (1) displays an appropriate copyright notice, and (2)
+tells the user that there is no warranty for the work (except to the
+extent that warranties are provided), that licensees may convey the
+work under this License, and how to view a copy of this License. If
+the interface presents a list of user commands or options, such as a
+menu, a prominent item in the list meets this criterion.
+
+#### 1. Source Code.
+
+The "source code" for a work means the preferred form of the work for
+making modifications to it. "Object code" means any non-source form of
+a work.
+
+A "Standard Interface" means an interface that either is an official
+standard defined by a recognized standards body, or, in the case of
+interfaces specified for a particular programming language, one that
+is widely used among developers working in that language.
+
+The "System Libraries" of an executable work include anything, other
+than the work as a whole, that (a) is included in the normal form of
+packaging a Major Component, but which is not part of that Major
+Component, and (b) serves only to enable use of the work with that
+Major Component, or to implement a Standard Interface for which an
+implementation is available to the public in source code form. A
+"Major Component", in this context, means a major essential component
+(kernel, window system, and so on) of the specific operating system
+(if any) on which the executable work runs, or a compiler used to
+produce the work, or an object code interpreter used to run it.
+
+The "Corresponding Source" for a work in object code form means all
+the source code needed to generate, install, and (for an executable
+work) run the object code and to modify the work, including scripts to
+control those activities. However, it does not include the work's
+System Libraries, or general-purpose tools or generally available free
+programs which are used unmodified in performing those activities but
+which are not part of the work. For example, Corresponding Source
+includes interface definition files associated with source files for
+the work, and the source code for shared libraries and dynamically
+linked subprograms that the work is specifically designed to require,
+such as by intimate data communication or control flow between those
+subprograms and other parts of the work.
+
+The Corresponding Source need not include anything that users can
+regenerate automatically from other parts of the Corresponding Source.
+
+The Corresponding Source for a work in source code form is that same
+work.
+
+#### 2. Basic Permissions.
+
+All rights granted under this License are granted for the term of
+copyright on the Program, and are irrevocable provided the stated
+conditions are met. This License explicitly affirms your unlimited
+permission to run the unmodified Program. The output from running a
+covered work is covered by this License only if the output, given its
+content, constitutes a covered work. This License acknowledges your
+rights of fair use or other equivalent, as provided by copyright law.
+
+You may make, run and propagate covered works that you do not convey,
+without conditions so long as your license otherwise remains in force.
+You may convey covered works to others for the sole purpose of having
+them make modifications exclusively for you, or provide you with
+facilities for running those works, provided that you comply with the
+terms of this License in conveying all material for which you do not
+control copyright. Those thus making or running the covered works for
+you must do so exclusively on your behalf, under your direction and
+control, on terms that prohibit them from making any copies of your
+copyrighted material outside their relationship with you.
+
+Conveying under any other circumstances is permitted solely under the
+conditions stated below. Sublicensing is not allowed; section 10 makes
+it unnecessary.
+
+#### 3. Protecting Users' Legal Rights From Anti-Circumvention Law.
+
+No covered work shall be deemed part of an effective technological
+measure under any applicable law fulfilling obligations under article
+11 of the WIPO copyright treaty adopted on 20 December 1996, or
+similar laws prohibiting or restricting circumvention of such
+measures.
+
+When you convey a covered work, you waive any legal power to forbid
+circumvention of technological measures to the extent such
+circumvention is effected by exercising rights under this License with
+respect to the covered work, and you disclaim any intention to limit
+operation or modification of the work as a means of enforcing, against
+the work's users, your or third parties' legal rights to forbid
+circumvention of technological measures.
+
+#### 4. Conveying Verbatim Copies.
+
+You may convey verbatim copies of the Program's source code as you
+receive it, in any medium, provided that you conspicuously and
+appropriately publish on each copy an appropriate copyright notice;
+keep intact all notices stating that this License and any
+non-permissive terms added in accord with section 7 apply to the code;
+keep intact all notices of the absence of any warranty; and give all
+recipients a copy of this License along with the Program.
+
+You may charge any price or no price for each copy that you convey,
+and you may offer support or warranty protection for a fee.
+
+#### 5. Conveying Modified Source Versions.
+
+You may convey a work based on the Program, or the modifications to
+produce it from the Program, in the form of source code under the
+terms of section 4, provided that you also meet all of these
+conditions:
+
+-   a) The work must carry prominent notices stating that you modified
+    it, and giving a relevant date.
+-   b) The work must carry prominent notices stating that it is
+    released under this License and any conditions added under
+    section 7. This requirement modifies the requirement in section 4
+    to "keep intact all notices".
+-   c) You must license the entire work, as a whole, under this
+    License to anyone who comes into possession of a copy. This
+    License will therefore apply, along with any applicable section 7
+    additional terms, to the whole of the work, and all its parts,
+    regardless of how they are packaged. This License gives no
+    permission to license the work in any other way, but it does not
+    invalidate such permission if you have separately received it.
+-   d) If the work has interactive user interfaces, each must display
+    Appropriate Legal Notices; however, if the Program has interactive
+    interfaces that do not display Appropriate Legal Notices, your
+    work need not make them do so.
+
+A compilation of a covered work with other separate and independent
+works, which are not by their nature extensions of the covered work,
+and which are not combined with it such as to form a larger program,
+in or on a volume of a storage or distribution medium, is called an
+"aggregate" if the compilation and its resulting copyright are not
+used to limit the access or legal rights of the compilation's users
+beyond what the individual works permit. Inclusion of a covered work
+in an aggregate does not cause this License to apply to the other
+parts of the aggregate.
+
+#### 6. Conveying Non-Source Forms.
+
+You may convey a covered work in object code form under the terms of
+sections 4 and 5, provided that you also convey the machine-readable
+Corresponding Source under the terms of this License, in one of these
+ways:
+
+-   a) Convey the object code in, or embodied in, a physical product
+    (including a physical distribution medium), accompanied by the
+    Corresponding Source fixed on a durable physical medium
+    customarily used for software interchange.
+-   b) Convey the object code in, or embodied in, a physical product
+    (including a physical distribution medium), accompanied by a
+    written offer, valid for at least three years and valid for as
+    long as you offer spare parts or customer support for that product
+    model, to give anyone who possesses the object code either (1) a
+    copy of the Corresponding Source for all the software in the
+    product that is covered by this License, on a durable physical
+    medium customarily used for software interchange, for a price no
+    more than your reasonable cost of physically performing this
+    conveying of source, or (2) access to copy the Corresponding
+    Source from a network server at no charge.
+-   c) Convey individual copies of the object code with a copy of the
+    written offer to provide the Corresponding Source. This
+    alternative is allowed only occasionally and noncommercially, and
+    only if you received the object code with such an offer, in accord
+    with subsection 6b.
+-   d) Convey the object code by offering access from a designated
+    place (gratis or for a charge), and offer equivalent access to the
+    Corresponding Source in the same way through the same place at no
+    further charge. You need not require recipients to copy the
+    Corresponding Source along with the object code. If the place to
+    copy the object code is a network server, the Corresponding Source
+    may be on a different server (operated by you or a third party)
+    that supports equivalent copying facilities, provided you maintain
+    clear directions next to the object code saying where to find the
+    Corresponding Source. Regardless of what server hosts the
+    Corresponding Source, you remain obligated to ensure that it is
+    available for as long as needed to satisfy these requirements.
+-   e) Convey the object code using peer-to-peer transmission,
+    provided you inform other peers where the object code and
+    Corresponding Source of the work are being offered to the general
+    public at no charge under subsection 6d.
+
+A separable portion of the object code, whose source code is excluded
+from the Corresponding Source as a System Library, need not be
+included in conveying the object code work.
+
+A "User Product" is either (1) a "consumer product", which means any
+tangible personal property which is normally used for personal,
+family, or household purposes, or (2) anything designed or sold for
+incorporation into a dwelling. In determining whether a product is a
+consumer product, doubtful cases shall be resolved in favor of
+coverage. For a particular product received by a particular user,
+"normally used" refers to a typical or common use of that class of
+product, regardless of the status of the particular user or of the way
+in which the particular user actually uses, or expects or is expected
+to use, the product. A product is a consumer product regardless of
+whether the product has substantial commercial, industrial or
+non-consumer uses, unless such uses represent the only significant
+mode of use of the product.
+
+"Installation Information" for a User Product means any methods,
+procedures, authorization keys, or other information required to
+install and execute modified versions of a covered work in that User
+Product from a modified version of its Corresponding Source. The
+information must suffice to ensure that the continued functioning of
+the modified object code is in no case prevented or interfered with
+solely because modification has been made.
+
+If you convey an object code work under this section in, or with, or
+specifically for use in, a User Product, and the conveying occurs as
+part of a transaction in which the right of possession and use of the
+User Product is transferred to the recipient in perpetuity or for a
+fixed term (regardless of how the transaction is characterized), the
+Corresponding Source conveyed under this section must be accompanied
+by the Installation Information. But this requirement does not apply
+if neither you nor any third party retains the ability to install
+modified object code on the User Product (for example, the work has
+been installed in ROM).
+
+The requirement to provide Installation Information does not include a
+requirement to continue to provide support service, warranty, or
+updates for a work that has been modified or installed by the
+recipient, or for the User Product in which it has been modified or
+installed. Access to a network may be denied when the modification
+itself materially and adversely affects the operation of the network
+or violates the rules and protocols for communication across the
+network.
+
+Corresponding Source conveyed, and Installation Information provided,
+in accord with this section must be in a format that is publicly
+documented (and with an implementation available to the public in
+source code form), and must require no special password or key for
+unpacking, reading or copying.
+
+#### 7. Additional Terms.
+
+"Additional permissions" are terms that supplement the terms of this
+License by making exceptions from one or more of its conditions.
+Additional permissions that are applicable to the entire Program shall
+be treated as though they were included in this License, to the extent
+that they are valid under applicable law. If additional permissions
+apply only to part of the Program, that part may be used separately
+under those permissions, but the entire Program remains governed by
+this License without regard to the additional permissions.
+
+When you convey a copy of a covered work, you may at your option
+remove any additional permissions from that copy, or from any part of
+it. (Additional permissions may be written to require their own
+removal in certain cases when you modify the work.) You may place
+additional permissions on material, added by you to a covered work,
+for which you have or can give appropriate copyright permission.
+
+Notwithstanding any other provision of this License, for material you
+add to a covered work, you may (if authorized by the copyright holders
+of that material) supplement the terms of this License with terms:
+
+-   a) Disclaiming warranty or limiting liability differently from the
+    terms of sections 15 and 16 of this License; or
+-   b) Requiring preservation of specified reasonable legal notices or
+    author attributions in that material or in the Appropriate Legal
+    Notices displayed by works containing it; or
+-   c) Prohibiting misrepresentation of the origin of that material,
+    or requiring that modified versions of such material be marked in
+    reasonable ways as different from the original version; or
+-   d) Limiting the use for publicity purposes of names of licensors
+    or authors of the material; or
+-   e) Declining to grant rights under trademark law for use of some
+    trade names, trademarks, or service marks; or
+-   f) Requiring indemnification of licensors and authors of that
+    material by anyone who conveys the material (or modified versions
+    of it) with contractual assumptions of liability to the recipient,
+    for any liability that these contractual assumptions directly
+    impose on those licensors and authors.
+
+All other non-permissive additional terms are considered "further
+restrictions" within the meaning of section 10. If the Program as you
+received it, or any part of it, contains a notice stating that it is
+governed by this License along with a term that is a further
+restriction, you may remove that term. If a license document contains
+a further restriction but permits relicensing or conveying under this
+License, you may add to a covered work material governed by the terms
+of that license document, provided that the further restriction does
+not survive such relicensing or conveying.
+
+If you add terms to a covered work in accord with this section, you
+must place, in the relevant source files, a statement of the
+additional terms that apply to those files, or a notice indicating
+where to find the applicable terms.
+
+Additional terms, permissive or non-permissive, may be stated in the
+form of a separately written license, or stated as exceptions; the
+above requirements apply either way.
+
+#### 8. Termination.
+
+You may not propagate or modify a covered work except as expressly
+provided under this License. Any attempt otherwise to propagate or
+modify it is void, and will automatically terminate your rights under
+this License (including any patent licenses granted under the third
+paragraph of section 11).
+
+However, if you cease all violation of this License, then your license
+from a particular copyright holder is reinstated (a) provisionally,
+unless and until the copyright holder explicitly and finally
+terminates your license, and (b) permanently, if the copyright holder
+fails to notify you of the violation by some reasonable means prior to
+60 days after the cessation.
+
+Moreover, your license from a particular copyright holder is
+reinstated permanently if the copyright holder notifies you of the
+violation by some reasonable means, this is the first time you have
+received notice of violation of this License (for any work) from that
+copyright holder, and you cure the violation prior to 30 days after
+your receipt of the notice.
+
+Termination of your rights under this section does not terminate the
+licenses of parties who have received copies or rights from you under
+this License. If your rights have been terminated and not permanently
+reinstated, you do not qualify to receive new licenses for the same
+material under section 10.
+
+#### 9. Acceptance Not Required for Having Copies.
+
+You are not required to accept this License in order to receive or run
+a copy of the Program. Ancillary propagation of a covered work
+occurring solely as a consequence of using peer-to-peer transmission
+to receive a copy likewise does not require acceptance. However,
+nothing other than this License grants you permission to propagate or
+modify any covered work. These actions infringe copyright if you do
+not accept this License. Therefore, by modifying or propagating a
+covered work, you indicate your acceptance of this License to do so.
+
+#### 10. Automatic Licensing of Downstream Recipients.
+
+Each time you convey a covered work, the recipient automatically
+receives a license from the original licensors, to run, modify and
+propagate that work, subject to this License. You are not responsible
+for enforcing compliance by third parties with this License.
+
+An "entity transaction" is a transaction transferring control of an
+organization, or substantially all assets of one, or subdividing an
+organization, or merging organizations. If propagation of a covered
+work results from an entity transaction, each party to that
+transaction who receives a copy of the work also receives whatever
+licenses to the work the party's predecessor in interest had or could
+give under the previous paragraph, plus a right to possession of the
+Corresponding Source of the work from the predecessor in interest, if
+the predecessor has it or can get it with reasonable efforts.
+
+You may not impose any further restrictions on the exercise of the
+rights granted or affirmed under this License. For example, you may
+not impose a license fee, royalty, or other charge for exercise of
+rights granted under this License, and you may not initiate litigation
+(including a cross-claim or counterclaim in a lawsuit) alleging that
+any patent claim is infringed by making, using, selling, offering for
+sale, or importing the Program or any portion of it.
+
+#### 11. Patents.
+
+A "contributor" is a copyright holder who authorizes use under this
+License of the Program or a work on which the Program is based. The
+work thus licensed is called the contributor's "contributor version".
+
+A contributor's "essential patent claims" are all patent claims owned
+or controlled by the contributor, whether already acquired or
+hereafter acquired, that would be infringed by some manner, permitted
+by this License, of making, using, or selling its contributor version,
+but do not include claims that would be infringed only as a
+consequence of further modification of the contributor version. For
+purposes of this definition, "control" includes the right to grant
+patent sublicenses in a manner consistent with the requirements of
+this License.
+
+Each contributor grants you a non-exclusive, worldwide, royalty-free
+patent license under the contributor's essential patent claims, to
+make, use, sell, offer for sale, import and otherwise run, modify and
+propagate the contents of its contributor version.
+
+In the following three paragraphs, a "patent license" is any express
+agreement or commitment, however denominated, not to enforce a patent
+(such as an express permission to practice a patent or covenant not to
+sue for patent infringement). To "grant" such a patent license to a
+party means to make such an agreement or commitment not to enforce a
+patent against the party.
+
+If you convey a covered work, knowingly relying on a patent license,
+and the Corresponding Source of the work is not available for anyone
+to copy, free of charge and under the terms of this License, through a
+publicly available network server or other readily accessible means,
+then you must either (1) cause the Corresponding Source to be so
+available, or (2) arrange to deprive yourself of the benefit of the
+patent license for this particular work, or (3) arrange, in a manner
+consistent with the requirements of this License, to extend the patent
+license to downstream recipients. "Knowingly relying" means you have
+actual knowledge that, but for the patent license, your conveying the
+covered work in a country, or your recipient's use of the covered work
+in a country, would infringe one or more identifiable patents in that
+country that you have reason to believe are valid.
+
+If, pursuant to or in connection with a single transaction or
+arrangement, you convey, or propagate by procuring conveyance of, a
+covered work, and grant a patent license to some of the parties
+receiving the covered work authorizing them to use, propagate, modify
+or convey a specific copy of the covered work, then the patent license
+you grant is automatically extended to all recipients of the covered
+work and works based on it.
+
+A patent license is "discriminatory" if it does not include within the
+scope of its coverage, prohibits the exercise of, or is conditioned on
+the non-exercise of one or more of the rights that are specifically
+granted under this License. You may not convey a covered work if you
+are a party to an arrangement with a third party that is in the
+business of distributing software, under which you make payment to the
+third party based on the extent of your activity of conveying the
+work, and under which the third party grants, to any of the parties
+who would receive the covered work from you, a discriminatory patent
+license (a) in connection with copies of the covered work conveyed by
+you (or copies made from those copies), or (b) primarily for and in
+connection with specific products or compilations that contain the
+covered work, unless you entered into that arrangement, or that patent
+license was granted, prior to 28 March 2007.
+
+Nothing in this License shall be construed as excluding or limiting
+any implied license or other defenses to infringement that may
+otherwise be available to you under applicable patent law.
+
+#### 12. No Surrender of Others' Freedom.
+
+If conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License. If you cannot convey a
+covered work so as to satisfy simultaneously your obligations under
+this License and any other pertinent obligations, then as a
+consequence you may not convey it at all. For example, if you agree to
+terms that obligate you to collect a royalty for further conveying
+from those to whom you convey the Program, the only way you could
+satisfy both those terms and this License would be to refrain entirely
+from conveying the Program.
+
+#### 13. Use with the GNU Affero General Public License.
+
+Notwithstanding any other provision of this License, you have
+permission to link or combine any covered work with a work licensed
+under version 3 of the GNU Affero General Public License into a single
+combined work, and to convey the resulting work. The terms of this
+License will continue to apply to the part which is the covered work,
+but the special requirements of the GNU Affero General Public License,
+section 13, concerning interaction through a network will apply to the
+combination as such.
+
+#### 14. Revised Versions of this License.
+
+The Free Software Foundation may publish revised and/or new versions
+of the GNU General Public License from time to time. Such new versions
+will be similar in spirit to the present version, but may differ in
+detail to address new problems or concerns.
+
+Each version is given a distinguishing version number. If the Program
+specifies that a certain numbered version of the GNU General Public
+License "or any later version" applies to it, you have the option of
+following the terms and conditions either of that numbered version or
+of any later version published by the Free Software Foundation. If the
+Program does not specify a version number of the GNU General Public
+License, you may choose any version ever published by the Free
+Software Foundation.
+
+If the Program specifies that a proxy can decide which future versions
+of the GNU General Public License can be used, that proxy's public
+statement of acceptance of a version permanently authorizes you to
+choose that version for the Program.
+
+Later license versions may give you additional or different
+permissions. However, no additional obligations are imposed on any
+author or copyright holder as a result of your choosing to follow a
+later version.
+
+#### 15. Disclaimer of Warranty.
+
+THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY
+APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT
+HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT
+WARRANTY OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT
+LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR
+A PARTICULAR PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND
+PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE PROGRAM PROVE
+DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, REPAIR OR
+CORRECTION.
+
+#### 16. Limitation of Liability.
+
+IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
+WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR
+CONVEYS THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
+INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES
+ARISING OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT
+NOT LIMITED TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR
+LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM
+TO OPERATE WITH ANY OTHER PROGRAMS), EVEN IF SUCH HOLDER OR OTHER
+PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.
+
+#### 17. Interpretation of Sections 15 and 16.
+
+If the disclaimer of warranty and limitation of liability provided
+above cannot be given local legal effect according to their terms,
+reviewing courts shall apply local law that most closely approximates
+an absolute waiver of all civil liability in connection with the
+Program, unless a warranty or assumption of liability accompanies a
+copy of the Program in return for a fee.
+
+END OF TERMS AND CONDITIONS
+
+### How to Apply These Terms to Your New Programs
+
+If you develop a new program, and you want it to be of the greatest
+possible use to the public, the best way to achieve this is to make it
+free software which everyone can redistribute and change under these
+terms.
+
+To do so, attach the following notices to the program. It is safest to
+attach them to the start of each source file to most effectively state
+the exclusion of warranty; and each file should have at least the
+"copyright" line and a pointer to where the full notice is found.
+
+        <one line to give the program's name and a brief idea of what it does.>
+        Copyright (C) <year>  <name of author>
+
+        This program is free software: you can redistribute it and/or modify
+        it under the terms of the GNU General Public License as published by
+        the Free Software Foundation, either version 3 of the License, or
+        (at your option) any later version.
+
+        This program is distributed in the hope that it will be useful,
+        but WITHOUT ANY WARRANTY; without even the implied warranty of
+        MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the
+        GNU General Public License for more details.
+
+        You should have received a copy of the GNU General Public License
+        along with this program.  If not, see <http://www.gnu.org/licenses/>.
+
+Also add information on how to contact you by electronic and paper
+mail.
+
+If the program does terminal interaction, make it output a short
+notice like this when it starts in an interactive mode:
+
+        <program>  Copyright (C) <year>  <name of author>
+        This program comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
+        This is free software, and you are welcome to redistribute it
+        under certain conditions; type `show c' for details.
+
+The hypothetical commands \`show w' and \`show c' should show the
+appropriate parts of the General Public License. Of course, your
+program's commands might be different; for a GUI interface, you would
+use an "about box".
+
+You should also get your employer (if you work as a programmer) or
+school, if any, to sign a "copyright disclaimer" for the program, if
+necessary. For more information on this, and how to apply and follow
+the GNU GPL, see <http://www.gnu.org/licenses/>.
+
+The GNU General Public License does not permit incorporating your
+program into proprietary programs. If your program is a subroutine
+library, you may consider it more useful to permit linking proprietary
+applications with the library. If this is what you want to do, use the
+GNU Lesser General Public License instead of this License. But first,
+please read <http://www.gnu.org/philosophy/why-not-lgpl.html>.

+# ReplayMod
+A Minecraft mod to record game sessions and replay them afterwards from any perspective.
+
+## Building
+Make sure your sub-projects are up-to-date: `git submodule update --init --recursive`
+
+For each branch you visit the first time, running `./gradlew setupDecompWorkspace` is necessary. 
+This will also be necessary if the `replaymod_at.cfg` file has been changed (getting errors about code that is trying 
+to access private fields is a good indication that this has happened).
+
+### No IDE
+You can build the mod by running `./gradlew :build`. You can then find the final jar files in `build/libs/`.
+
+### IntelliJ
+For the initial setup run `./gradlew preshadowJar idea genIntellijRuns`.
+You also need to enable the Mixin annotation processor:
+1. Go to File -> Settings -> Build, Execution, Deployment -> Compiler -> Annotation Processors
+2. Tick "Enable annotation processing"
+3. Add a new entry to the "Annotation Processor options"
+4. Set the name to "reobfSrgFile" and the value to "$path/build/mcp-srg.srg" where you replace $path with the full 
+path to the folder containing the gradlew file
+
+Whenever you switch to another branch, you can either just run `./gradlew preshadowJar idea` or instead run 
+`./gradlew preshadowJar copySrg` and then refresh the gradle project from within IntelliJ.
+
+### Eclipse
+
+## Development
+### Branches
+New features are developed on the `1.8` branch and merged upwards for release. Larger features are developed on their
+own branch that is based on `1.8` and then merged back once it's finished.
+
+Features or bug fixes that apply only to a specific Minecraft version are fixed on the branch corresponding to that 
+version and reverted when merging upwards.
+
+Both subprojects follow a similar branching model.
+
+The user documentation (`docs` folder) is only committed to on the current development branch. Any changes committed on
+a branch for a more recent Minecraft version are not kept up to date on the website and should only be
+of importance once support for the previous Minecraft version is dropped.
+
+The `master` branch is solely to be used for the `version.json` file that contains a list of all versions
+used by the clients to check for updates of this mod.
+
+### Versioning
+The ReplayMod uses the versioning scheme outlined [here](http://mcforge.readthedocs.io/en/latest/conventions/versioning/)
+with three changes:
+- No `MAJORAPI`, the ReplayMod does not provide any external API
+- "Updating to a new Minecraft version" should not increment `MAJORMOD`, we maintain one version of the ReplayMod
+for each version of Minecraft and all these versions share the same feature set (and most bugs). We therefore try to
+keep the version name the same for all of them (with the exception of `MCVERSION` of course). This also means that the
+"Multiple Minecraft Version" section does not apply.
+- For pre-releases the shorter `-bX` is used instead of `-betaX`
+
+When a new version is (pre-)release, a new annotated tag should be added with the name of the version and the
+`versions.json` file in the `master` branch should be updated. To simplify this process the gradle task `doRelease` can
+be used: `./gradlew -PreleaseVersion=1.8-2.0.0-rc1 doRelease`. It will create the tag and update the version.json
+accordingly.
+
+Care should be taken that the updated `version.json` is not pushed before a jar file is available on the
+download page (or Jenkins) as it will inform the users of the update.
+
+### Bugs
+Bugs in the mod are tracked via [Bugzilla](https://bugs.replaymod.com/).
+GitHub should only be used for issues that are generally not likely to affect any end users.
+
+Bug numbers in commits such as `(fixes #42)` refer to Bugzilla unless noted otherwise.
+
+## License
+The ReplayMod is provided under the terms of the GNU General Public License Version 3 or (at your option) any later version.
+See `LICENSE.md` for the full license text.

+### Documentation
+The documentation at [replaymod.com/docs](https://www.replaymod.com/docs/) is generated from
+`content.md` using a custom Node.js script.
+
+Using an image directly after a header will show it to the right of the text and will show the following
+text as its caption.
+
+Block quotes (`> Quote`) are used to highlight sections of texts: `> **Note:** This is important.`
+
+Images should be available in two formats: jpg, which is loaded by default and the original png which
+is loaded when the user clicks on the image. Note that some might only be available as jpg right now
+as their original was lost.  
+Animated images should be available in webm (vp9) format which is displayed by default and as a gif which is used as
+the fallback for browsers that lack webm support.  
+In `content.md`, the default version is used.
+
+Make sure you have [npm]() installed.
+For the initial setup run `npm install`.
+Run `node build` to generate the html.
+
+Note: The template used for the live version is different and the one here is only for convenient testing.

+# Installation [installing]
+## Installing the Replay Mod [replaymod]
+The **ReplayMod** requires **Minecraft Forge** to be installed.
+
+Depending on your **Replay Mod** version we recommend the following **Forge** versions:
+
+- Replay Mod 2.0.0 or later for Minecraft 1.11: Forge [1.11-13.19.1.2189](https://files.minecraftforge.net/maven/net/minecraftforge/forge/index_1.11.html)
+- Replay Mod 2.0.0 or later for Minecraft 1.10.2: Forge [1.10.2-12.18.2.2099](https://files.minecraftforge.net/maven/net/minecraftforge/forge/index_1.10.2.html)
+- Replay Mod 2.0.0 or later for Minecraft 1.9.4: Forge [1.9.4-12.17.0.1976](https://files.minecraftforge.net/maven/net/minecraftforge/forge/index_1.9.4.html)
+- Replay Mod 2.0.0 or later for Minecraft 1.8: Forge [1.8-11.14.4.1563](https://files.minecraftforge.net/maven/net/minecraftforge/forge/index_1.8.html)
+- Replay Mod 1.0.8 or older for Minecraft 1.8: Forge [1.8-11.14.3.1450](http://files.minecraftforge.net/maven/net/minecraftforge/forge/index_1.8.html)
+
+Other Forge Versions might, but don't necessarily work.
+
+If you don't know how to install Forge, follow [this tutorial](https://www.youtube.com/watch?v=4i7-RystzC4).
+
+After installing Forge, simply put the downloaded `ReplayMod.jar` file in the `/mods` folder of your Minecraft directory.
+
+> **Note:** The **Replay Mod** is entirely client side and can not be installed on the servers you play on.
+
+## Installing FFmpeg [ffmpeg]
+To use the **Replay Mod**'s [Rendering Feature](#replaying-render), you need to have FFmpeg installed.
+
+### Windows [windows]
+Download the latest **FFmpeg Static Build** for your architecture from <http://ffmpeg.zeranoe.com/builds/>.  
+Then, extract the downloaded `.7z` file in the folder you want to install FFmpeg in.
+
+Next, download this **Batch Script** to quickly install FFmpeg: <https://replaymod.com/files/ffmpeg-path-installer.bat>
+
+> **Note:** If your browser warns you about the download, dismiss the message. It's a simple Batch Script which won't damage your computer.
+
+Put the downloaded script into the folder where you extracted FFmpeg and run itt by double-clicking it.
+If you see a success message in the console, you've sucessfully installed **FFmpeg**!
+
+Alternatively, starting with ReplayMod 2.0.0-b5, you can also extract the downloaded `.7z` file into a `ffmpeg` folder
+(you have to create it, it doesn't exist by default) in your `.minecraft` folder. No need to run any **Batch Script**.
+The FFmpeg executable should end up at `.minecraft/ffmpeg/bin/ffmpeg.exe`.
+
+### Mac OSX [mac]
+On OSX, you can install **FFmpeg** with **[Homebrew](http://brew.sh/)** using `brew install ffmpeg`.
+
+Alternatively, you can download the latest static build from <https://ffmpeg.org/> and copy the ffmpeg executable to `/usr/local/bin`.
+
+### Linux [linux]
+On Linux, you can install **FFmpeg** using your system's package manager, for example using `apt install ffmpeg`.
+If in doubt, consult the documentation of your distribution.
+
+## Compatibility with other Mods [compatibility]
+### General information [general]
+In General, the Replay Mod _should_ be compatible with most Forge Mods.
+
+### Shaders Mod [shaders]
+[Karyonix' Shaders Mod](http://www.minecraftforum.net/forums/mapping-and-modding/minecraft-mods/1286604-shaders-mod-updated-by-karyonix)
+is no longer compatible with Minecraft Forge starting with 1.9.4. As such it is not compatible with the Replay Mod either.
+Please use [Optifine](https://optifine.net/) instead.
+
+### Custom Main Menu [custom-main-menu]
+The [Custom Main Menu](https://mods.curse.com/mc-mods/minecraft/226406-custom-main-menu) mod is often used in mod packs to customize their Main Menu with a button layout fitting the background image, links to their website / bug tracker and similar.
+If you are familiar with it, the button ids for the Replay Mod are: **17890234** (text: `replaymod.gui.replayviewer`), **17890237** (text: `replaymod.gui.replayeditor`) and **17890236** (text: `replaymod.gui.replaycenter`)
+
+Due to the nature of this Custom Main Menu mod, buttons added to the Main Menu by 3rd party mods like the **Replay Mod** will not show up by default.  
+Thus, to access the Replay Viewer/Editor/Center, you need to manually configure the position for those buttons.  
+To do so, you need to modify the Custom Main Menu configuration file.
+Usually, you can find it at `.minecraft/config/CustomMainMenu/mainmenu.json` (if you're using a mod pack launcher, it normally has its own .minecraft folder).  
+For an explanation of this config file, have a look at Custom Main Menu's page.
+
+You can find a list of already modified config files [here](https://gist.github.com/Johni0702/3f3fab81dbf7ada83d045d9fe8f345aa).
+
+## Troubleshooting [troubleshooting]
+If you need help installing the **Replay Mod** or **FFmpeg**, please read [this forum thread](https://www.replaymod.com/forum/thread/220) 
+by [bela333](https://www.replaymod.com/user/bela333) - it covers most of the problems that users encountered so far.
+
+## Settings [settings]
+To access the **Replay Mod Settings** from the Main Menu click the **"Mods"** button, select the **Replay Mod** from the list and
+the click the **"Config"** button.
+
+When in a Replay, you can either bind a hotkey to the **Replay Mod Settings** in Minecraft's Control settings
+or use the hotkey GUI by clicking on the arrow button in the lower left corner.
+
+# Recording [recording]
+![](img/recording-indicator.jpg)
+The **Recording Indicator** which is displayed while recording
+
+Recording Replays is the core feature of the **Replay Mod**.
+
+Recording a Replay is really simple: If enabled in the **Replay Settings**, the Mod will automatically record all of your gaming sessions.  
+You will be notified that the Recording started by a **Chat Message**. Chat Messages can be disabled in the **Replay Settings**.  
+In the upper left corner, a **Recording Indicator** will be displayed unless disabled in the **Replay Settings** while you are recording.
+
+While Recording, you can set [Event Markers](#replaying-markers) using the `M` key.
+
+Upon exiting your Server/Singleplayer World, you might be asked to wait a couple of seconds until saving the Replay has been finished.  
+Congratulations, your Replay is now accessible via the **Replay Viewer**!
+
+# Replaying [replaying]
+![](img/replay-viewer.jpg)
+The **Replay Viewer** with several recorded Replays
+
+To watch one of your Replays, open up the **Replay Viewer** from the **Main Menu** and select the desired Replay.
+Then, press the "Load" button.
+
+In the **Replay Viewer**, you can also **rename**, **delete** and **upload** your **Replay Files**.
+
+## Movement [movement]
+### Basic Controls [basic]
+While in the Replay, you can freely move around using the movement keys (`WASD, Space, Shift` by default).
+You can move through block similar to Spectator Mode.
+
+Using the **Mouse Wheel**, you can modify your flying speed. Scrolling **up** causes you to fly faster, while scrolling **down** slows you down.
+
+If you prefer the camera to be controlled similar to vanilla Creative Mode, you can change that in the **Replay Settings**.
+
+### Camera Roll [roll]
+![](img/camera-tilted.jpg)
+A Screenshot taken with a **tilted camera**
+
+While in a Replay, you can tilt the Camera.
+
+By default, pressing `J` will tilt the screen clockwise, and pressing `L` will tilt the screen counterclockwise.  
+Using `K`, you can reset the Camera Roll.
+
+When holding the `Ctrl` key (`Cmd` key on Mac) while tilting, you can tilt slower and more precisely.
+
+> **Hint:** Most of the Keybindings mentioned in this documentation can be changed in Minecraft's **Control Menu**.
+
+### Spectating Entities [spectating]
+You can spectate any living entitiy (including players) while in a Replay. When looking at an entity, a crosshair will be visible.
+
+By right-clicking, you will start spectating the entity. If you want to stop spectating the entity, use your Sneak Key (`Shift`).
+
+## Controlling Time [time]
+### Replay Speed [speed]
+![](img/real-timeline.jpg)
+The **Play/Pause button**, **Speed Slider** and **Replay Timeline** hightlighted
+
+In the upper left corner of you screen, there is a **Play/Pause button** (Shortcut: `P`), using which you can entirely pause the time of the Replay.  
+All Entities, Particles and Block Updates will be frozen until you resume. You can fly through a paused Replay as usual.
+
+Next to the Play/Pause Button, there is a **Speed Slider**. Using the **Speed Slider**, you can control how fast the time in your Replay passes.  
+The minimum Speed value is **0.1 times** the normal Minecraft Tick Speed, and the maximum Speed is **8 times** as fast.
+
+### Jumping in Time [travel]
+To the right of the Speed Slider, there is the **Replay Timeline**.
+On the Replay Timeline, you see a yellow cursor indicating your current position in the Replay.  
+By clicking somewhere on this Timeline, you will travel in time towards the specified point in time.  
+Please note that it takes longer to do larger steps in time or to jump backwards in time.
+
+## Camera Paths [paths]
+### Introduction [intro]
+While in a Replay, you can create controlled **Camera Movements** using the Mods's **Keyframe System**.  
+Those Camera Paths can be rendered to a video later (see [Rendering](#replaying-render)).
+
+Camera Paths are inspired by the [PixelCam Mod](http://www.minecraftforum.net/forums/mapping-and-modding/minecraft-mods/2327429-pixelcam-camera-studio-for-minecraft-1-8) which is based on the Camera Studio Mod.
+
+The **Replay Mod Keyframe System** is similar to many Video Editing Software's Keyframe Systems.
+If you're new to Keyframe Systems, try reading [this Wikipedia article](https://en.wikipedia.org/wiki/Key_frame).
+
+### Keyframe Timeline [timeline]
+![](img/keyframe-timeline.jpg)
+The **Keyframe Timeline** highlighted
+
+All of the Keyframes which define a Camera Path are placed on the **Keyframe Timeline**.
+The Keyframe Timeline is below the [Replay Timeline](#replaying-time-travel).
+
+The **Keyframe Timeline** is 10 Minutes long, meaning a Camera Path can take up to 10 Minutes.
+You can zoom in and out on the Keyframe Timeline using the `+` and `-` buttons next to it.
+
+Other than the **Replay Timeline**, the **Keyframe Timeline**'s time values are not relative to the Replay's point of time, but refer to **real time**.  
+If two Keyframes are 5 seconds apart, the Camera Path will take 5 seconds to interpolate between those Keyframes.
+
+You can drag Keyframes on the **Keyframe Timeline** by left-clicking them, holding the mouse button and moving your mouse.
+
+### Position Keyframes [place]
+The basic components of a Camera Path are **Position Keyframes**.
+A Position Keyframe stores a **Camera Position** (x, y, z, yaw, pitch, roll).
+
+You can set a **Position Keyframe** using the "Add Position Keyframe" ![Green Rhomb](img/position-keyframe-button.png) button.  
+A **Position Keyframe** initially contains the state the Camera was in when creating the Keyframe.
+
+On the **Keyframe Timeline**, a **Position Keyframe** will appear at the cursors's current position.  
+This Keyframe is selected automatically, and the **Position Keyframe Button** will turn red.
+By clicking the **Position Keyframe Button** again, the selected **Position Keyframe** will be removed.
+
+By adding multiple **Position Keyframes** on the **Keyframe Timeline**, you can create a simple **Camera Path**.  
+Using the [Path Preview](#replaying-paths-place-preview), you can preview your **Camera Path**.
+
+> **Hint:** By right-clicking a **Position Keyframe** on the **Keyframe Timeline**, you can jump to this Keyframe's Position.
+
+#### Path Interpolation [interpolation]
+![](img/cubic-path.gif)
+A **Camera Path** using **Cubic Interpolation**
+
+![](img/linear-path.gif)
+The same **Camera Path** using **Linear Interpolation**
+
+By default, Camera Paths follow a smooth curve through all of the set **Position Keyframes**.
+This curve is generated using [Cubic Spline Interpolation](https://en.wikipedia.org/wiki/Spline_interpolation).  
+If you wish to disable smooth interpolation and want to make the Path follow straight lines instead, change the **Path Interpolation Setting** in the **Replay Settings**.
+
+You can easily toggle between **Linear** and **Cubic Interpolation** using the `O` key.
+
+#### Path Preview [preview]
+![](img/path-preview-icon.jpg)
+While the **Path Preview** is enabled, this camera symbol is displayed in the lower right corner of the screen.
+
+![](img/path-preview.jpg)
+A normal **Path Preview**
+
+Using the `H` key, you can toggle a **visual representation** of your Camera Path.
+If enabled, you will see a **Red Line** in the World following the Camrea Path.
+
+The [Path Interpolation Setting](#replaying-paths-place-interpolation) is respected in this preview.
+
+By moving the cursor on the **Keyframe Timeline**, you can see the Camera's current positon and view direction on the **Path Preview**.
+
+### Time Keyframes [time]
+**Time Keyframes** can be used to precisely control time travelling during a **Camera Path**.
+
+> Every Time Keyframe represents a timestamp in the Replay itself.
+
+You can set a **Time Keyframe** using the "Add Time Keyframe" ![Green Hourglass](img/time-keyframe-button.png) button.  
+A **Time Keyframe** initially contains the Replay's point in time when creating the Keyframe.
+
+When playing the **Camera Path**, the Replay's time will interpolate between the set **Time Keyframes** in the Keyframes' intervals. Two **Time Keyframes** with the same Timestamp will freeze the Replay time for the duration of their interval.
+
+> **Hint:** By right-clicking a **Time Keyframe** on the **Keyframe Timeline**, you can jump to this Keyframe's Timestamp Value.
+
+> **Note:** Travelling backwards in time is not supported during **Camera Paths**. Do not add a **Time Keyframe** containing an earlier point in time after another **Time Keyframe**.
+
+To play your first **Camera Path**, click the **Play Button** next to the **Keyframe Timeline**.  
+By default, the **Camera Path** starts from the Cursor Position on the Keyframe Timeline.
+By clicking while holding the `Ctrl` key (`Cmd` key on Mac), you can however start from the beginning regardless of the Cursor Position.
+
+#### Synchronizing Timelines [sync]
+Using the `V` key, you can **synchronize** the **Keyframe Timeline** with the time that passed since the last **Time Keyframe**'s timestamp.
+
+This means that pressing `V` moves the **Keyframe Timeline**'s cursor to the position where placing a **Time Keyframe** would result in a **Replay Speed** of the **Speed Slider's current value** between the newly placed and the last **Time Keyframe**.
+
+If holding `Shift` while synchronizing, it will be synchronized as if the **Speed Slider's value** was **1.0**.
+
+### Spectator Keyframes [spectator]
+![](img/path-preview-spectator.jpg)
+A **Path Preview** with **Spectator Keyframes**
+
+While [spectating an entity](#replaying-movement-spectating), the "Add Position Keyframe" button becomes an "Add Spectator Keyframe" ![Blue Rhomb](img/spectator-keyframe-button.png) button.
+
+To sucessfully spectate an entity, you always need at least two **Spectator Keyframes** created while spectating the same entity.  
+On the **Keyframe Timeline**, the periods during which you are spectating an entity are marked with a blue line.
+
+To leave a spectated entity during a camera path, simply add a normal **Position Keyframe**.
+
+### Editing Keyframes [edit]
+![](img/keyframe-editor.jpg)
+The **Keyframe Editor** for a **Position Keyframe**
+
+You can edit any Keyframe by **double-clicking** it on the Keyframe Timeline.
+A new GUI Screen will open which allows you to modify the Keyframe's properties.
+
+On the lower part of the screen, you can precisely set the Keyframe's position on the **Keyframe Timeline**.  
+Above that, you can modify Keyframe specific settings, for example its Position value.
+
+### Removing Keyframes [remove]
+Using the `DELETE` key, you can remove the currently selected Keyframe.  
+Alternatively, while a Keyframe is selected, its connected Button turns red, and clicking it removes the Keyframe as well.
+
+> **Note:** If you use an Apple Computer with a built-in keyboard, you  may need to press `FN + DELETE` instead.
+
+### Keyframe Repository [repository]
+![](img/keyframe-repository.jpg)
+The **Keyframe Repository** with two **Path Presets**
+
+[YouTube](IYrzbbIzWPw)
+
+Using the `X` key, you can open the **Keyframe Repository**. Every Replay File has a separate Keyframe Repository which can contain several **Keyframe Presets**.
+
+To save the Keyframes currently on your Timeline, click the **"Save as..."** button.
+You can change a Preset's name, select it from the list and click the **"Rename"** button.
+To load a Keyframe Preset, select a Preset from the list and click the **"Load"** button.
+Using the **"Remove"** button, you can permanently delete a Keyframe Preset from the **Keyframe Repository**.
+
+## Custom Objects [objects]
+
+> Custom Objects are not available in the 2.0.0 versions. They are expected to return eventually.
+
+[YouTube](_Xdpg828fbE)
+
+### Introduction [introduction]
+**Custom Objects** are mainly meant for **video creators**. They allow you to add any image into the Replay World and animate its Position, Opacity and much more.
+
+Instead of using [Motion Tracking](https://en.wikipedia.org/wiki/Match_moving) to add text or pictures to a video, you can directly add these to the rendered file.
+
+### Adding Assets [assets]
+![](img/asset-manager.jpg)
+The **Asset Manager** with an example Asset
+
+In order to create **Custom Objects**, you first have to add **Assets** to your Replay File.  
+Therefore, open the **Asset Manager** using the `G` key.
+
+In the **Asset Manager**, you can add **Image Files (.png, .jpg and more)**, so-called **Assets**, to the Replay.  
+When clicking the **"Add"** button, a File Chooser will show up. Select the image file you want to use.  
+You can give the Asset a custom name using the Text Input Field in the top right corner.
+
+All of the Assets you added can be used by **Custom Objects**.

+### Creating Custom Objects [creating]
+![](img/object-manager.jpg)
+The **Object Manager** with some **Animation Keyframes**
+
+Using the `F` key, you can open the **Object Manager**. Initially there won't be any Objects in the **Object List**, but you can simply add an Object using the **"Add"** button.
+
+After doing so, you can name the newly created **Custom Object** using the Text Field in the upper right corner.  
+To define which **Asset File** (i.e. image) the **Custom Object** should use, select the desired **Asset** from the dropdown beneath the Name Input.
+
+If you leave the **Object Manager**, you should see the image in the World somwhere near your position.
+
+### Animating Custom Objects [animating]
+![](img/custom-object-animated.gif)
+An animated **Custom Image Object**.
+
+Of course, you don't want the image to stay at that position.
+ herefore, open the **Object Manager** again and select the **Custom Object** you want to modify.  
+On the lower half of the screen you will see mutliple **Input Fields**, using which you can modify various settings
+(so-called **Transformations**), for example the Object's **Position**, **Scale**, **Orientation** and **Opacity**.
+
+When editing these values, you'll notice that on the TImeline to the right, Keyframes appear.
+You can set and remove Keyframes for specific settings using its "Add Keyframe" button on the very left of the screen.
+
+The **Object Manager's Keyframe System** is very similar to the **Position Keyframe** and **Time Keyframe** System.
+
+During a **Camera Path**, the **Custom Objects** will interpolate their **Transformation Values** like **Position Keyframes** are interpolated.  
+While outside the **Object Manager** you can preview the Objects' position by moving the cursor on the **Keyframe Timeline** - the Objects will interpolate to the position they'll be at that timestamp during the **Camera Path**.
+
+Once you got the hang of it, you'll be able to quickly animate **Custom Objects**.
+
+## Rendering [render]
+With the **Replay Mod**, you can render **Camera Paths** to videos **without** using a screen recording tool like Fraps.  
+To get started, first [set up your Camera Path](#replaying-paths) as described in the previous chapters.
+Then, press the **"Render Camera Path"** button in the upper left corner.
+
+### Rendering Method [method]
+The **Replay Mod** does not only allow you to render "normal" vidoes as you see them on YouTube everyday,
+you can also render **360 degree videos**, **3D videos** and more.  
+To change the rendering method, use the dropdown on the upper half of the **Render Settings Screen**.
+
+#### Default Rendering [default]
+![](img/render-default.jpg)
+A frame exported using **Default Rendering**
+
+Renders the video in the specified resolution. Fastest Rendering Option.
+
+#### Stereoscopic Rendering [stereoscopic]
+![](img/render-stereoscopic.jpg)
+A frame exported using **Stereoscopic Rendering**
+
+Renders the video as a [stereoscopic](https://en.wikipedia.org/wiki/Stereoscopy) (side-by-side) 3D move, usable by different 3D technologies. The image for one eye is half the width of the video.
+
+#### Cubic Rendering [cubic]
+![](img/render-cubic.jpg)
+A frame exported using **Cubic Rendering**
+
+Renders the video with a **360 degree panoramic view**, using [Cubic Projection](http://wiki.panotools.org/Cubic_Projection).
+This is usable by several 360 degree video players (and the **Oculus Rift**), for example [VR Player](https://vrplayer.codeplex.com/).  
+While **Cubic Videos** can't be used for **YouTube 360° Videos**, it takes less time to render them, so if your player 
+is compatible with **Cubic Projection** anyway, you can use this setting.
+
+#### Equirectangular Rendering [equirectangular]
+![](img/render-equirectangular.jpg)
+A frame exported using **Equirectangular Rendering**
+
+Renders the video with a 360 degree panoramic view, using [Equirectangular Projection](http://wiki.panotools.org/Equirectangular_Projection).
+This is usable by [YouTube's new 360 degree video function](https://support.google.com/youtube/answer/6178631?hl=en), and several video players (and the **Oculus Rift**), for example [VR Player](https://vrplayer.codeplex.com/).
+
+> **Note:** In order for **YouTube** to recognize 360 Degree Videos, you have to inject some Metadata. Follow [this guide](https://support.google.com/youtube/answer/6178631?hl=en) for a tutorial.
+
+### Video Settings [settings]
+![](img/rendersettings-video.jpg)
+The **Video Render Settings** Screen
+
+After you chose the **Rendering Mode** you want to use, you can further customize the rendered video.
+
+#### Video Resolution [resolution]
+Below the **Render Method** Dropdown, you can enter the desired **Video Resolution** (Width * Height).
+You can enter any resolution there, but make sure to use reasonable values.
+
+Common Video Resolutions for **Default Rendering** are:
+
+- 720p - 1280 * 720
+- 1080p - 1920 * 1080
+- 4k - 3840 * 2160
+
+---
+
+When using **Stereoscopic Rendering**, please note that the entered **Width** value is the final video's width.
+Because **Stereoscopic Videos** have two frames next to each other, you therefore need to **double** the video width,
+so if you want a **Full HD Stereoscopic Video**, you have to enter **3840 * 1080**.
+
+---
+
+Videos in **Equirectangular Projection** always need to have an **Aspect Ratio** of **2:1**.
+
+Please note that you should generally use a high resolution when exporting **Equirectangular Videos**, as the Video will be mapped onto a spherical surface in the Viewer you're using. To get a decent looking video, we recommend a resolution of **4320 * 2160**.
+
+> **Note:** If you're re-rendering Equirectangular footage (e.g. using a video editing software like Premiere), make sure to export it at a **2:1** aspect ratio - otherwise it will look strange in 360 degrees.
+
+#### Video Framerate [framerate]
+
+#### Video Encoding and Quality [quality]
+![](img/quality-comparison.jpg)
+A comparison between the quality of the **MP4 Hight, Default and Potato** Quality Presets.
+
+Below the **Render Method Dropdown**, there is another Dropdown Menu for **Encoding Presets**.
+
+> **Note:** If you simply want to render an MP4 video in good quality, don't change these settings.
+
+There are **7 Encoding Presets** you can choose from:
+
+- **MP4 - Default Quality**  
+  Renders an **MP4 video** encoded with the **x264 codec** in **Default Quality**.
+  This is default Encoding Preset, as it exports a video with good quality and a relativly low file size.
+- **MP4 - High Quality**  
+  Renders an **MP4 video** encoded with the **x264 codec** in **High Quality**.
+  Rendered videos have a relatively high file size, but their quality is almost lossless. This is useful for video producers who have to encode (render) their footage several times.
+- **MP4 - Potato Quality**  
+  Renders an **MP4 video** encoded with the **x264 codec** in **Very Low Quality**.
+  While the video itself looks really bad, the file size is tiny and therefore this preset can be used for test renders.
+- **MP4 - Custom Bitrate**  
+  If this Preset is chosen, the **Bitrate Input Field** gets enabled and you can define the video's bitrate yourself.
+  The rendered video is an **MP4 video** encoded with the **x264 codec**.
+- **WEBM - Custom Bitrate**  
+  If this Preset is chosen, the **Bitrate Input Field** gets enabled and you can define the video's bitrate yourself.
+  The rendered video is a **webm video** encoded with the **vp8 codec**.  
+  **webm video files** are useful if you want to upload footage directly to streaming services like YouTube, 
+  as they usually don't have to convert **vp8-encoded videos** when processing them.
+- **MKV - Lossless**  
+  Renders an **MKV video** encoded with the **x264 codec** in **Lossless Quality**.
+  While these video files are of perfect quality, most **non-FFmpeg-based video players and video editing software** (e.g. QuickTime Player, Sony Vegas and Adobe Premiere) can't play these videos. Therefore, you should instead use the **MP4 - High Quality** preset in most cases.
+- **PNG Sequence**  
+  Exports the sequence as individual frames in the **PNG Format**.  
+  **Warning:** This can create a huge amount of files, so make sure to save them in a separate folder.
+
+### Advanced Settings [advanced]
+![](img/rendersettings-advanced.jpg)
+The **Advanced Render Settings**
+
+#### Render Nametags [nametags]
+If you don't want to see Entity's Nametags in the rendered video, simply un-tick the checkbox. Hidden Nametags also include Nametags of **Armor Stands** and **Mobs**, **not only Players**!
+
+#### Stabilize Camera [stabilize]
+This setting is only applicable for **Cubic Rendering** and **Equirectangular Rendering**.  
+Because you can rotate the camera in **360 degree viewers**, a tilted camera persepctive leads to a strange user experience:
+If the user looks around, his view might appear to be tilted because the camera looked up or down.
+Therefore, it is recommended to **always stabilize the camera's Pitch and Roll** using the repsective checkboxes.
+
+[Example 360° video **without stabilized Camera Pitch**](https://www.youtube.com/watch?v=lHGSG-0CVZw)  
+[Example 360° video **with stabilized Camera Pitch and Roll**](https://www.youtube.com/watch?v=mtBehojUotQ)
+
+#### Chroma Keying [chroma]
+![](img/chromasky.jpg)
+A screenshot of a video rendered with a **Red Chroma Key Setting**
+
+This is an experimental setting for video producers which allows you to change the sky color to a fixed color.
+Using a **Video Editing Software** like **Adobe After Effects** or **Sony Vegas**, you can change the sky color to transparency and add your own footage as sky. Read more about **Chroma Keying** [here](https://en.wikipedia.org/wiki/Chroma_key).
+
+> **Note:** For best results, you should **disable clouds** before rendering, as they are transparent.
+
+### Command Line Settings [commandline]
+![](img/rendersettings-commandline.jpg)
+The **Command Line Render Settings**
+
+
+> **Note**: This is for advanced users only. If you do not know what your're doing, leave these settings as they are.
+
+The **Replay Mod** runs [FFmpeg](http://ffmpeg.org/) via the **Command Line** to encode videos.
+
+You can customize both the **executed Command** and the **Command Line Arguments** in the **Command Line Settings** part of the **Render Settings Screen**.
+
+#### Custom Command [command]
+If you leave the left input field blank, `ffmpeg` will be used as **command**. If you haven't set your **PATH variable** to link to your FFmpeg distribution, simply enter the full path to your FFmpeg executable (e.g. `C:/ffmpeg/ffmpeg.exe` or `/usr/local/bin/ffmpeg`).
+
+#### Command Line Arguments [arguments]
+In the right input field, you can input custom **Command Line Arguments** to be used in the console.
+
+Each of the **Encoding Presets** basically represents a set of **Command Line Arugments** which are used with the **ffmpeg Command**.
+Customizing these **Command Line Arguments** allows you to use a specific codec or quality setting and much more.  
+If you need an introduction to **ffmpeg Command Line Arguments**, read the [FFmpeg documentation](http://ffmpeg.org/ffmpeg.html).
+
+Before passing the given **Command Line Arguments** to the **ffmpeg Command**, the **Replay Mod** replaces the following placeholders with your inputs in the **Render Settings Screen**:
+- **%WIDTH%**  
+  The video's width
+- **%HEIGHT%**  
+  The video's height
+- **%FPS%**  
+  The video's framerate
+- **%FILENAME%**  
+  The video's filename **without the extension**. This should be surrounded with quotation marks `"`, as the filename might contain spaces.  
+  As the **ffmpeg Command** is always executed from the target file's parent directory, %FILENAME% does **not** contain the file's full path.
+- **%BITRATE%**  
+  The video's bitrate in **kilobytes per second**. As the %BITRATE% placeholder already contains the **value identifier "K"**,
+  you don't have to take care of the bitrate value's format.
+
+### Rendering Performance [performance]
+![](img/rendering-screen.jpg)
+The Screen which is displayed while a video is being rendered
+
+By clicking the **Render Button** in the lower right corner, you start **Default Performance Rendering**. Usually, this is perfectly satisfying regarding rendering speed, but you can increase it slightly using **High Performance Rendering**.
+
+To use **High Performance Rendering**, hold down the `Ctrl` key  (`Cmd` key on Mac) while clicking the **Render Button**.  
+**High Performance Rendering** has the following changes to improve rendering speed:
+ - Rendering Process, Estimated Time Left and Button Clicks are not recalculated after every rendered frame,
+   but only after one rendered seconds (e.g. every 60 frames when rendering with 60fps)
+ - Resizing the Minecraft Window does not update the Rendering Gui
+
+### Troubleshooting [troubleshooting]
+
+> If you have trouble with rendering, please first consult the Documentation before asking for help in the Forums.
+
+#### No FFmpeg installation found [ffmpeg]
+![](img/ffmpeg-missing.jpg)
+The error screen that is displayed when no FFmpeg installation could be found
+
+If the **Replay Mod** tells you to install FFmpeg even though you already have, you have to manually tell the **Replay Mod** where your FFmpeg executable is located.
+
+First, get the full path to your `ffmpeg.exe` (on Windows) or `ffmpeg` executable (on Mac/Linux).  
+On Windows, this path  might look like `C:/ffmpeg/ffmpeg.exe`.
+
+Then, open the **"Command Line Settings" Tab** in the Render Settings and paste this path into the **left input field** and retry rendering.
+
+#### Crash while rendering [crash]
+If Minecraft crashes after a few frames of rendering, it most likely means the **FFmpeg** didn't like the **Command Line Arguments** you passed.
+If you customized the Command Line Arguments manually, re-check them - it's probably your own fault.
+
+> **Hint:** In your .minecraft folder, you'll find a file called `export.log` which contains information about FFmpeg's rendering process.
+
+If you did **not** customize the **Command Line Arguments**, you might have entered some insanely high (or low) values e.g. for Bitrate or Video Resolution. Try again with other, more reasonable values.
+
+## Ambient Lighting [lighting]
+![](img/ambient-lighting-comparison.jpg)
+The same setting, onace with **Ambient Lighting** enabled, once with **Ambient Lighting** disabled
+
+![](img/eyecon.jpg)
+While **Ambient Lighting** is enabled, this eye symbol is displayed in the lower right corner of the screen.
+
+If you have a Replay in a dark setting (for example at nighttime, or in a cave) and **Brightness: Bright** just isn't bright enough for you, you can toogle **Ambient Lighting** using the `Z` key (`Y` on some keyboards).
+
+This works as a replacement for the **Night Vision Potion Effect**, without the side effect of a weird sky color.
+
+## Player Overview [overview]
+![](img/player-overview.jpg)
+The **Player Overview** Screen
+
+Using the `B` key, you can open the **Player Overview**. In the **Player Overview**, you see a list of all currently loaded **Players** in the Replay.
+
+By clicking on a player's **Name or Head**, you can **spectate** this player.
+
+Next to each player, there's a **checkbox** using which you can toggle the player's **visibility**.
+This way, you can hide certain players from the Replay.  
+Below the individual checkboxes, there are two checkbox buttons - one to **hide all players** and one to **show all players**.
+
+If you want to **save the player visibility settings**, check **"Remember Hidden Players" checkbox**.
+If checked, invisible players will stay invisible after closing the Replay (this can of course be reverted),
+otherwise all of the players are visible again after reloading the Replay.
+
+## Thumbnails [thumbnail]
+![](img/default-thumb.jpg)
+The **Default Thumbnail** which is used if no Thumbnail was created
+
+While in a Replay, you can use the `N` key to create a **Thumbnail** of the current Replay.  
+A **Thumbnail** is a Screenshot which should give the viewer a good impression of your Replay's content.
+
+**Thumbnails** are important when uploading a Replay to the **Replay Center**,
+as other users are much more likely to download your Replay if they can see a preview of it.  
+They also help keeping your **Replay Viewer** clear and structured.
+
+If no **Thumbnail** is set for a Replay, the **Default Thumbnail** will be displayed in the **Replay Viewer** and in the **Replay Center**.
+
+## Event Markers [markers]
+![](img/marker-timeline.jpg)
+The **Replay Timeline** with several **Event Markers**
+
+Long Replays easily get really clunky and difficult to handle.
+Therefore, **Event Markers** are a simple way to mark important events in your Replay.
+
+While [recording a Replay](#recording), you can press the `M` key anytime to set an **Event Marker**.
+This **Event Marker** remembers the **Position** where you've added it and will later,
+while watching a Replay, be displayed on the **Replay Timeline**.
+
+While viewing a Replay, you can jump to an **Event Marker**'s Position and Timestamp by right-clicking it on the **Replay Timeline**.
+
+You can also add new **Event Markers** while viewing a Replay using the `M` key as well.
+
+You can name **Event Markers** by double-clicking them. 
+When hovering over the **Event Marker**, its name is displayed.
+This way, it's even simpler to add structure to your Replays.
+
+You can **delete an Event Marker** by clicking it once to select it and then pressing the `DELETE` key.
+
+# Replay Center [center]
+The **Replay Center** is where you can **share** your **Minecraft Moments** with others and discover awesome **Replays by other Users**.  
+To be able to use the **Replay Center**, you need an **account on ReplayMod.com**.
+
+## Authentication [auth]
+![](img/auth-login.jpg)
+The **Login Screen** which is displayed upon startup
+
+![](img/auth-register.jpg)
+The **Register Screen**
+
+When starting Minecraft with the **Replay Mod** installed, you will be asked to login to **ReplayMod.com**.  
+If you don't want to use the **Replay Center**, you can click the **"Skip" Button** to continue without logging in.
+
+If you want to browse other users' **Replays** and **share your own Replays** however, you need to **Register an account**.
+
+> **Note:** By registering an Account on **ReplayMod.com**, you agree to the Website's [Terms of Service](https://www.replaymod.com/legal/terms)
+
+Please note that you can only create **one ReplayMod.com Account per Minecraft Account**, so choose your username wisely.
+
+Once you've registered, you're automatically going to be logged in. The Mod **remembers your login** until you manually log out from the **Replay Center**, so it won't ask you upon every startup if you logged in once.
+
+## Replay Files [files]
+![](img/replay-center.jpg)
+The **Replay Center** in the Mod
+
+Once you've logged in, you can use the **"Replay Center" Button** in the Main Menu to access the **Replay Center**.
+
+In the upper half of the screen, there are **5 Buttons** for **5 Tabs** of the **Replay Center**:
+- **Recent**  
+  Shows the most recently uploaded Replays in the **Replay Center**
+- **Best**  
+  Shows the Replays with the **best rating and most downloads**
+- **Downloaded**  
+  Shows all of the Replays you've downloaded locally
+- **Favorited**  
+  Shows all of the Replays you favorited
+- **Search**  
+  Allows you to search for specific Replays
+
+When you've found an insteresting looking Replay, you can download it using the **"Download" Button** in the lower left corner.
+After downloading, you'll automatically join the Replay.
+
+After you've downloaded a Replay, you can rate and favorite it in the **Replay Center** using the respective buttons.
+
+> You are encouraged to rate Replays after you downloaded them to help promoting the best Replays.
+
+## Upload Replays [upload]
+![](img/replay-upload.jpg)
+The **Replay Upload Screen**
+
+You can share your own **Replay Files** with other users in the **Replay Center**.
+Therefore, click the **"Upload" Button** in the **Replay Viewer** after selecting a Replay.
+
+In the **Replay Upload Screen** there are **6 input fields**:
+- **Replay Name**  
+  The Replay's Name in the Replay Center
+- **Replay Description**  
+  A description of what happens in the Replay. Try to give the user a good impression why your Replay is worth downloading.
+- **Category**  
+  The Replay's Category, one of the following: **Survival**, **Build**, **Minigame**, **Miscellaneous**. If none of the other categories fit, use **Miscellaneous**.
+- **Tags**  
+  One or more tags that fit your replay, spearated by comma. **Example tags:** pvp,battle,redstone,creative
+- **Hide Server IP**  
+  If you've recorded a Replay on a private Server, you can remove the Server IP by checking the respective checkbox.
+- **Thumbnail**  
+  While you can't directly edit the Thumbnail when uploading, it is highly recommended that
+  you [create a Thumbnail](#replaying-thumbnail) before sharing your Replay.
+  Replays without a Thumbnail are much less likely to be downloaded by other users.
+
+When uploading a Replay File, make sure to follow the [Replay Center Rules](https://www.replaymod.com/rules).
+
+# Frequently Asked Questions [faq]
+
+### Do I need a ReplayMod.com Account to use the mod?
+You only need a ReplayMod.com Account to access the [Replay Center](#center).
+All of the other features are also available offline.
+
+### For how long can I record?
+Theoretically, a Replay File can be up to **24 days, 20 hours, 30 minutes and 23 seconds** long - which is a timespan you'll probably never reach.
+
+### How many chunks around me does the Mod record?
+If you're playing in **Singleplayer**, all of the loaded chunks within your **Render Distance** are recorded.  
+If you're on a server, this depends on the **view-distance** setting in the **server.properties** file, which is set to **11 Chunks** by default.
+
+The Replay Mod of course records every **loaded**, not only the **rendered** chunks. Therefore, chunks behind your back are recorded as well.
+
+### Why can't I start recording in the middle of a session?
+Due to the way the **Replay Mod** works, you need to start recording when joining a **Server** or **World** - otherwise some data which the **Replay Files** need is missing.
+
+### How does recording affect my FPS?
+Usually, recording a Replay does **_not_** affect your framerate, and it also doesn't lead to lag on servers.  
+We've tested the Mod on a low-end notebook with only **3GB of ram**, and everything worked fine.
+
+### How big are the files the Replay Mod records?
+The file size of the recorded **.mcpr files** greatly depends on the amount of world data the replay contains.  
+A Replay in which you travelled around and discovered a lot of terrain is significantly larger than a Replay which was recorded in a void world.
+
+An average Replay File of **10 Minutes duration** usually is between **2MB and 10MB large**.
+Replays recorded on **Minigame Servers** with lots of particle effects and world changes might be larger.
