 ## 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. 
+For compiling 1.7.10, you must run `./gradlew :jGui:1.7.10:setupDecompWorkspace :1.7.10:setupDecompWorkspace` once after the initial clone. This may take quite some time.
-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/`.
+You can build the mod by running `./gradlew build` (or just `./gradlew bundleJar`). You can then find the final jar files in `versions/$MCVERSION/build/libs/`.
+You can also build single versions by running `./gradlew :1.8:build` (or just `./gradlew :1.8:bundleJar`) (builds the MC 1.8 version).
 
 ### IntelliJ
-For the initial setup run `./gradlew preshadowJar idea genIntellijRuns`.
+Ensure you have at least IDEA 2020.1.
-You also need to enable the Mixin annotation processor:
+Build the mod via Gradle as explained above at least once (`./gradlew compileJava` should be sufficient). This will ensure that the sources for all MC versions are generated.
-1. Go to File -> Settings -> Build, Execution, Deployment -> Compiler -> Annotation Processors
+Then import the Gradle project from within IDEA: File -> Open -> build.gradle -> Open as Project
-2. Tick "Enable annotation processing"
+Finally configure IDEA to build everything by itself instead of delegating it to Gradle (cause that is slow): File -> Settings -> Build, Execution, Deployment -> Build Tools -> Gradle -> Build and run using: IntelliJ IDEA
-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.

 ## Development

+Main development happens on the `develop` branch, snapshots are built from this branch.
-
+The `stable` branch contains the most recent release.
-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.
 
+### The Preprocessor
+To support multiple Minecraft versions with the ReplayMod, a [JCP](https://github.com/raydac/java-comment-preprocessor)-inspired preprocessor is used.
+It has by now acquired a lot more sophisticated features to make it as noninvasive as possible.
+Please read the [preprocessor's README](https://github.com/ReplayMod/preprocessor/blob/master/README.md) to understand how it works.

 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 generally be used to report bugs.
-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.
+In the past, bugs were tracked via [Bugzilla](https://bugs.replaymod.com/), so bug numbers in commits prior to 2020 such as `(fixes #42)` generally referred to Bugzilla unless noted otherwise.

+You can find Fabric and the installation instructions [here](https://fabricmc.net/use/).
-Other Forge Versions might, but don't necessarily work.

-Then, extract the downloaded `.7z` file in the folder you want to install FFmpeg in.

-### 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]

-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.

+_Badlion Client_ offers a different ReplayMod that is not the same as this one.

+## Compatibility with other Mods [compatibility]
+### General information [general]
+In General, the Replay Mod _should_ be compatible with most Forge and Fabric Mods.
+
+### Shaders Mod [shaders]
+_Karyonix' Shaders Mod_ is no longer compatible with Minecraft Forge starting with 1.9.4. As such it is not compatible with the Replay Mod either.
+
+Below Minecraft 1.16 you can try _Optifine_ instead. Note however, that official support has ended and many versions break ReplayMod.
+
+On Minecraft 1.16.5 and up you can use _Iris_, which is fully supported. For the time being, you will have to use it with the custom _Sodium_ provided on our download page. The fix it includes is pending for the official version.
+
+### Custom Main Menu [custom-main-menu]
+The _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 id for the Replay Mod is: **17890234** (text: `replaymod.gui.replayviewer`).
+
+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.

+
+### RandomPatches [randompatches]
+Minecraft may crash if you try to use _RandomPatches_ together with ReplayMod. Try removing RandomPatches if Minecraft crashes on startup.
+
+### Sodium [sodium]
+ReplayMod can record when _Sodium_ is installed, but currently lacks the FREX Flawless Frames API to render. A modified build of _Sodium_, that supports this API, is available from the ReplayMod downloads, by clicking the `Click to show compatible Sodium versions` button.
+
+### Resource Loader [resourceloader]
+The _Resource Loader_ mod is not compatible with ReplayMod.
+
+### LiteLoader [liteloader]
+![](img/mutlimc-liteloader.jpg)
+The MultiMC interface to place ReplayMod above LiteLoader.
+
+![](img/multimc-addempty.jpg)
+The properties for the new *Empty*.
+
+_LiteLoader_ is known to cause issues due to the mixin version it contains.
+
+You can use MultiMC to workaround this problem.
+> The MultiMC `Edit` function requires that your computer has a default editor for json files associated.
+
+1: Create your instance then edit the instance  
+2: Click `Install Forge`  
+3: Click `Install LiteLoader`  
+4: Click `Add Empty`; use `ReplayMod` as name and `com.replaymod` as uid  
+5: Select the new *ReplayMod* and click `Edit`  
+6: Replace the contents with one of the below snippets  
+7: Save and close the text editor  
+8: Move *ReplayMod* up until it is **above** *LiteLoader*  
+9: Remove the ReplayMod jar from the mods folder if you installed it previously.
+
+** Snippet for 1.8.9 **  
+`{ "formatVersion": 1, "name": "ReplayMod", "uid": "com.replaymod", "version": "1.8.9-2.4.5", "libraries": [{ "name": "com.replaymod:replaymod:1.8.9-2.4.5", "MMC-absoluteUrl":  "https://minio.replaymod.com/replaymod/replaymod-1.8.9-2.4.5.jar" }]}`
