 ## Installing the Replay Mod [replaymod]
 The **ReplayMod** requires **Minecraft Forge** to be installed.
 
-For the use with the **Replay Mod**, we recommend using Forge Version `1.8-11.14.3.1450`, which can be downloaded [here](http://files.minecraftforge.net/maven/net/minecraftforge/forge/index_1.8.html)
+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 1.8: Forge [1.8-11.14.4.1563](https://files.minecraftforge.net/maven/net/minecraftforge/forge/index_1.8.html)

@@ -37,26 +48,35 @@ 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.
-However, due to the way that recording works, many Mods that add new Blocks, Mobs or Game Mechanics are not supported.  
-Mods that simply modify the client (like the [PixelCam Mod](http://www.minecraftforum.net/forums/mapping-and-modding/minecraft-mods/2327429-pixelcam-camera-studio-for-minecraft-1-8)
-or the [CommandGroups Mod](http://www.minecraftforum.net/forums/mapping-and-modding/minecraft-mods/2443430-command-groups-mod-order-label-and-color-command)) usually work.
-
-### Optifine [optifine]
-The **Replay Mod** is compatible with `Optifine 1.8.0 HD U D5`, which can be downloaded at <https://optifine.net/downloads>.  
-Other Optifine versions for Minecraft 1.8.0 might, but don't have to be compatible as well.
-
-> **Warning:** If you have Optifine installed, you **can not render videos** from within the Replay Mod.  
-This might change in future Replay Mod versions.
 
 ### Shaders Mod [shaders]
-You can use the Replay Mod together with [karyonix' Shaders Mod](http://www.minecraftforum.net/forums/mapping-and-modding/minecraft-mods/1286604-shaders-mod-updated-by-karyonix),
-but rendering videos results in **possible crashes** and **malformed videos**.
-Therefore, you have to **uninstall the Shaders Mod before rendering**.
+[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
