+## Supported Godot Versions
+
+GodotXterm aims to support the current stable release of Godot, but may lag slightly.
+Currently, Godot versions 3.4.x are supported with support for 3.5 coming soon.
+Versions 3.3.x are no longer officially supported but *may* work if the GDNative libraries are
+compiled using an older version of godot-cpp.

 ## Installation
