+# GDNative WebRTC plugin for Godot
+
+## Getting Started
+
+| **Download latest binary version** | [**GitHub**](https://github.com/godotengine/webrtc-native/releases) |
+| --- | --- |
+
+### Compiling
+
+Clone this repository with the following command to checkout all the dependencies: [godot-cpp](https://github.com/godotengine/godot-cpp), [openssl](https://www.openssl.org/) and [libdatachannel](https://github.com/paullouisageneau/libdatachannel) (and sub-dependencies).
+
+```
+$ git clone --recurse-submodules https://github.com/godotengine/webrtc-native.git
+```
+
+If you already checked out the branch use the following commands to update the dependencies:
+
+```
+$ git submodule update --init --recursive
+```
+
+### Compiling the extension.
+
+To build the GDExtension version of the plugin (Godot 4.1+) run the following command from the `webrtc-native` folder:
+
+```
+$ scons platform=<your platform>
+```
+
+This will build all the required dependencies into a single shared library.
+
+To build the "legacy" GDExtension version of the plugin (Godot 4.0) run the following command instead:
+
+```
+$ scons platform=<your platform> godot_version=4.0
+```
+
+To build the GDNative version of the plugin (Godot 3.x) run the following command instead:
+
+```
+$ scons platform=<your platform> godot_version=3
+```
+
+> Replace `<your platform>` with either `windows`, `linux`, `osx`, `android`, or `ios`.
+
+> Include `target=release` or `target=debug` for release or debug build (default is `debug`).
+
+The resulting library and associated `tres` or `gdextension` will be created in `bin/[extension|gdnative]/webrtc[_debug]` depending on the `target` and `godot_version`.
+
+You simply need to copy that folder to the root folder of your project. Note that you will have to build the library for all the desired export platforms.
+
+### License
+
+The `webrtc-native` plugin is licensed under the MIT license (see [LICENSE](https://github.com/godotengine/webrtc-native/blob/master/LICENSE)), while `libdatachannel` and its dependencies are licensed under other permissive open source licences. Please see [`thirdparty/README.md`](thirdparty/README.md) for more informations.
