+# Anima pluging for Godot 4
+
+This is the ready-to-be-installed [Anima](https://github.com/ceceppa/anima) addon for Godot4.
+
+## NOTE
+
+**The plugin is still in development and not all the feature works fine on Godot4.**
+
+This repository contains only the **addon** code without the demo and documentation and has been created to allow users to install the addon via the AssetLibrary.
+
+The development happens on the [godot-4](https://github.com/ceceppa/anima/tree/godot-4) branch of the main [anima repository](https://github.com/ceceppa/anima/). So, any issue or pull request needs to be open there.
+
+## Documentation
+
+WIP documentation is available [here](https://anima.ceceppa.me/docs/)
