+## Mouse Support
+
+:warning: This repository defaults to an EXPERIMENTAL mouse movement branch which is slated for eventual merge into ZMK, but is not guaranteed to be stable. For more information, see [beta testing](https://zmk.dev/docs/features/modules#beta-testing) and [PR #2477](https://github.com/zmkfirmware/zmk/pull/2477).

+If desired, edit your `config/west.yml` to switch back to `zmkfirmware`'s `main` branch:
