-        An Intellij platform plugin for developing Intellij plugins with Compose framework
+        The plugin provides a shared base for developing IntelliJ plugins with the
+        <a href="https://www.jetbrains.com/lp/compose/">Compose</a> UI framework.
+
+        The plugin is in the early stages of development. Please use with caution!
+
+        For now, it only provides Compose classes and native libraries for use at runtime,
+        so that multiple IntelliJ plugins can share Compose classes and Skia bindings.
