 Golang bindings for [raylib](http://www.raylib.com/), a simple and easy-to-use library to enjoy videogames programming.
 
+This is a fork of [gen2brain's `raylib-go` bindings](https://github.com/gen2brain/raylib-go) to add [DRM leasing](https://wayland.app/protocols/drm-lease-v1) support.
+
 raylib C source code is included and compiled together with bindings. Note that the first build can take a few minutes.
