-Most libraries (like ``bcm_host``) can just be replaced with stubs, because they don't need to do anything and aren't used by anything else. However, some libraries (like EGL and X11) might be used by some of MCPI-Reborn's dependencies (like GLFW) so instead of being replaced by a stub, each call is manually patched out from MCPI. A stub is still generated just in case that library isn't present on the system to silence linker errors, but it is only loaded if no other version is available.

+## Command Line Arguments
+
+### ``--version`` (Or ``-v``)
+If you run MCPI-Reborn with ``--version`` it will print its version to ``stdout``.
+
+### ``--print-available-feature-flags`` (Client Mode Only)
+If you run MCPI-Reborn with ``--print-available-feature-flags``, it will print the available feature flags to ``stdout`` and then immediately exit.
+
+The feature flags are printed in the following format:
 ```
 TRUE This Flag Is On By Default
 FALSE This Flag Is Off By Default
 ```
 
-## ``--only-generate`` (Server Mode Only)
+### ``--default`` (Client Mode Only)
+If you run MCPI-Reborn with ``--default``, it will skip the startup configuration dialogs and just use the default values.
+
+### ``--only-generate`` (Server Mode Only)
 If you run MCPI-Reborn with ``--only-generate``, it will immediately exit once world generation has completed. This is mainly used for automatically testing MCPI-Reborn.
+
+### ``--benchmark`` (Client Mode Only)
+If you run MCPI-Reborn with ``--benchmark``, it will enter a simple benchmark mode. This means automatically loading a newly generated world, then rotating the camera for a period of time. When it has finished, it will then exit and print the average FPS while the world was loaded. In this mode, all user input is blocked. However you can still modify rendering settings by changing feature flags.
+
+The world used will always be re-created on start and uses a hard-coded seed.
+
+## Environmental Variables
+
+### ``MCPI_DEBUG``
+This enables debug logging if it is set.
+
+### Client Mode Only
+If any of the following variables aren't set, one configuration dialog will open on startup for each unset variable.
+
+#### ``MCPI_FEATURE_FLAGS``
+This corresponds to ``--print-available-feature-flags``. This is just a list of all enabled feature flags separated by ``|``.
+
+For instance, the string ``Feature A|Feature B`` would enable both ``Feature A`` and ``Feature B`` and *disable every other available feature flag*.
+
+#### ``MCPI_RENDER_DISTANCE``
+This is the render distance. The possible values are: ``Far``, ``Normal``, ``Short``, and ``Tiny``.
+
+#### ``MCPI_USERNAME``
+This is the username.

 # Dedicated Server
 The dedicated server is a version of Minecraft: Pi Edition modified to run in a headless environment. It loads settings from a ``server.properties`` file.
 
-This server is also compatible with MCPE Alpha v0.6.1.
+This server is also compatible with MCPE Alpha v0.6.1[^1].
 
 ## Setup
 
 ### Debian Package
 To use, install and run ``minecraft-pi-reborn-server``. It will generate the world and ``server.properties`` in the current directory.
 
+### Docker Image
+An official Docker image is also provided: [thebrokenrail/minecraft-pi-reborn-server](https://hub.docker.com/r/thebrokenrail/minecraft-pi-reborn-server).
+
 ## Server Limitations
 * Player data is not saved because of limitations with MCPE LAN worlds
   * An easy workaround is to place your inventory in a chest before logging off
 * Survival Mode servers are incompatible with unmodded MCPI
+
+[^1]: The exception to this is buckets, those will crash MCPE players.

+# Sound
+One of MCPI-Reborn's main modifications is a sound-engine since MCPI doesn't include one by default[^1]. However, it can't be used out-of-box because MCPI doesn't contain any sound data and MCPI-Reborn can't include it because of copyright.
+
+MCPE's sound data can be extracted from any MCPE v0.6.1[^2] APK file, just place its `libminecraftpe.so` into `~/.minecraft-pi/overrides` and you should have sound!
+
+[^1]: The mute button is just leftover code from MCPE, it doesn't actually do anything in un-modded MCPI, however it is connected to MCPI-Reborn's sound-engine.
+[^2]: This isn't a hard limit, an MCPE v0.8.1 APK would probably work, but don't rely on it.

+# Example Mods
+This is an example of a mod that can be built using the modding SDK.
+
+* **Expanded Creative Mod**: This specific mod adds even more items and blocks to the Creative Inventory. It was originally by [@Bigjango13](https://github.com/bigjango13).
+* **Chat Commands Mod**: This specific mod makes an chat message starting with a ``/`` handled by the MCPI API.
+* **Recipes Mod**: This specific mod demos custom recipes.
+
+## The SDK
+The modding SDK is a collection of exported CMake targets that allows anyone to create their own MCPI mod!
+
+The SDK is copied to ``~/.minecraft-pi/sdk/lib/minecraft-pi-reborn-client/sdk/sdk.cmake`` whenever MCPI-Reborn is started.
+
+## How do I use this?
+```sh
+mkdir build
+cd build
+cmake ..
+cp libexpanded-creative.so ~/.minecraft-pi/mods
+```
