+      LavaLauncher is a simple launcher panel for Wayland desktops.
+
+      It displays a dynamically sized bar with user defined buttons. Buttons
+      consist of an image, which is displayed as the button icon on the bar, and
+      at least one shell command, which is executed when the user activates the
+      button.
+
+      Buttons can be activated with pointer and touch events.
+
+      A single LavaLauncher instance can provide multiple such bars, across
+      multiple outputs.
+
+      The Wayland compositor must implement the Layer-Shell and XDG-Output for
+      LavaLauncher to work.
