+## Godot Engine platform port for Haiku
+
+This is the platform port of [Godot Engine](https://godotengine.org) for the
+[Haiku](https://www.haiku-os.org) operating system.
+
+Haiku is not an officially supported platform in the main tree of Godot, so
+this port is kept separate so that it can be contributed to independently of
+Godot's main release cycle.
+
+It may imply that this port might not be functional for the latest versions of
+Godot. For the time being, neither the `3.2` branch nor the `master` branch are
+functional out-of-the-box on Haiku.
+
+We welcome all contributions from Haiku developers to ensure that each branch
+and Git tag of this repository work as expected with the matching branches and
+tags of the [Godot repository](https://github.com/godotengine/godot/).
+
+## Usage
+
+This code is meant to be copied as `platform/haiku` in the Godot Engine
+[source repository](https://github.com/godotengine/godot/) to make builds of
+Godot for Haiku.
+
+It can also be cloned as a Git submodule:
+
+```
+git clone https://github.com/godotengine/godot
+cd godot
+git submodule add https://github.com/godotengine/godot-haiku-platform platform/haiku
+```
+
+Be sure to use compatible branches for the Godot repository and the Haiku port.
+
+You can then compile Godot for Haiku with:
+
+```
+# Editor build, optimized.
+scons p=haiku tools=yes target=release_debug
+
+# Export template, debug.
+scons p=haiku tools=no target=release_debug
+# Export template, release.
+scons p=haiku tools=no target=release
+```
+
+## License
+
+This port is distributed under the MIT license, with the same copyright as the
+main Godot source repository.
+
+See [LICENSE.txt](/LICENSE.txt) for details, and
+[AUTHORS.md](https://github.com/godotengine/godot/blob/master/AUTHORS.md) in
