 ## Description
 
+This plugin is compatible with [xbar](https://xbarapp.com/) and [SwiftBar](https://github.com/swiftbar/SwiftBar), and provides a menubar app that creates a Lima menubar option with submenus for each Lima VM on your machine. For each VM, you can:
+
+- start/stop the VM
+- stop, start or remove stopped containers
+- pull or remove images from the VM
+
