+# Messages app
+
+**THIS APP IS CURRENTLY BETA**
+
+This app handles the display of messages and message notifications. It stores
+a list of currently received messages and allows them to be listed, viewed,
+and responded to.
+
+It is a replacement for the old `notify`/`gadgetbridge` apps.
+
+## Usage
