 ## Compatibility
 
-**Warning:** The GDExtension API is brand new in Godot 4.0, and is still
-considered in **beta** stage, despite Godot 4.0 itself being released.
+GDExtensions targeting an earlier version of Godot should work in later minor versions,
+but not vice-versa. For example, a GDExtension targeting Godot 4.2 should work just fine
+in Godot 4.3, but one targeting Godot 4.3 won't work in Godot 4.2.
 
-This applies to both the GDExtension interface header, the API JSON, and this
-first-party `godot-cpp` extension.
-
-Some compatibility breakage is to be expected as GDExtension and `godot-cpp`
-get more used, documented, and critical issues get resolved. See the
-[Godot issue tracker](https://github.com/godotengine/godot/issues?q=is%3Aissue+is%3Aopen+label%3Atopic%3Agdextension)
-and the [godot-cpp issue tracker](https://github.com/godotengine/godot-cpp/issues)
-for a list of known issues, and be sure to provide feedback on issues and PRs
-which affect your use of this extension.
+There is one exception to this: extensions targeting Godot 4.0 will _not_ work with
+Godot 4.1 and later.
+See [Updating your GDExtension for 4.1](https://docs.godotengine.org/en/latest/tutorials/migrating/upgrading_to_godot_4.1.html#updating-your-gdextension-for-godot-4-1).

+### cmake arguments
+
+`CMAKE_BUILD_TYPE`:         Compilation target (Debug or Release defaults to Debug)
+
+### godot-cpp cmake arguments
+- `GODOT_GDEXTENSION_DIR`:    Path to the directory containing GDExtension interface header and API JSON file
+- `GODOT_SYSTEM_HEADERS`:     Mark the header files as SYSTEM. This may be useful to suppress warnings in projects including this one.
+- `GODOT_WARNING_AS_ERROR`:   Treat any warnings as errors
+- `GODOT_USE_HOT_RELOAD`:     Build with hot reload support. Defaults to YES for Debug-builds and NO for Release-builds.
+- `GODOT_CUSTOM_API_FILE`:    Path to a custom GDExtension API JSON file (takes precedence over `gdextension_dir`)
+- `GODOT_PRECISION`:          Floating-point precision level ("single", "double")
+
+### Android cmake arguments
+- `CMAKE_TOOLCHAIN_FILE`:     The path to the android cmake toolchain ($ANDROID_NDK/build/cmake/android.toolchain.cmake)
+- `ANDROID_NDK`:              The path to the android ndk root folder
+- `ANDROID_TOOLCHAIN_NAME`:   The android toolchain (arm-linux-androideabi-4.9 or aarch64-linux-android-4.9 or x86-4.9 or x86_64-4.9)
+- `ANDROID_PLATFORM`:         The android platform version (android-23)
+

+
+## Examples
+```shell
+Builds a debug version:
+cmake .
+cmake --build .
+```
+Builds a release version with clang
+
+```shell
+CC=/usr/bin/clang CXX=/usr/bin/clang++ cmake -DCMAKE_BUILD_TYPE=Release -G "Unix Makefiles" .
+cmake --build .
+```
+Builds an android armeabi-v7a debug version:
+
+``` shell
+cmake -DCMAKE_TOOLCHAIN_FILE=$ANDROID_NDK/build/cmake/android.toolchain.cmake -DANDROID_NDK=$ANDROID_NDK \
+		-DANDROID_TOOLCHAIN_NAME=arm-linux-androideabi-4.9 -DANDROID_PLATFORM=android-23 -DCMAKE_BUILD_TYPE=Debug .
+cmake --build .
+```
+
+## Protip
+Generate the buildfiles in a sub directory to not clutter the root directory with build files:
+
+```shell
+mkdir build && cd build && cmake -G "Unix Makefiles" .. && cmake --build .
+```
+
+Ensure that you avoid exposing godot-cpp symbols - this might lead to hard to debug errors if you ever load multiple
+plugins using difference godot-cpp versions. Use visibility hidden whenever possible:
+```cmake
+set_target_properties(<all-my-plugin-related-targets> PROPERTIES CXX_VISIBILITY_PRESET hidden)
+```
+
+## Todo
+Test build for Windows, Mac and mingw.

-# Git hooks for Godot Engine
-
-This folder contains Git hooks meant to be installed locally by Godot Engine
-contributors to make sure they comply with our requirements.
-
-## List of hooks
-
-- Pre-commit hook for `clang-format`: Applies `clang-format` to the staged
-  files before accepting a commit; blocks the commit and generates a patch if
-  the style is not respected.
-  You may need to edit the file if your `clang-format` binary is not in the
-  `PATH`, or if you want to enable colored output with `pygmentize`.
-- Pre-commit hook for `black`: Applies `black` to the staged Python files
-  before accepting a commit.
-- Pre-commit hook for `make_rst`: Checks the class reference syntax using
-  `make_rst.py`.
-
-## Installation
-
-Copy all the files from this folder into your `.git/hooks` folder, and make
-sure the hooks and helper scripts are executable.
-
-#### Linux/MacOS
-
-The hooks rely on bash scripts and tools which should be in the system `PATH`,
-so they should work out of the box on Linux/macOS.
-
-#### Windows
-
-##### clang-format
-- Download LLVM for Windows (version 13 or later) from
-  <https://releases.llvm.org/download.html>
-- Make sure LLVM is added to the `PATH` during installation
-
-##### black
-- Python installation: make sure Python is added to the `PATH`
-- Install `black` - in any console: `pip3 install black`
