 C++ bindings for the Godot script API
 
-Note that the master branch in this repository is for use with Godot build from its latest master.
-If you need to support older versions of Godot use the relevant branch for that version in this repository.
+The instructions below feature the new NativeScript 1.1 class structure and will only work for modules created for Godot 3.1 and later. Use the following branches for older implementations:
