+	  mender-connect is a daemon responsible for handling
+	  bidirectional (websocket) communication with the Mender
+	  server. The daemon is responsible for implementing a range of
+	  troubleshooting features to the device as well as several
+	  enhancement to the mender-client.
+
+	  Mender Connect is loosely coupled with the Mender Client. The
+	  main information passed between mender-client and
+	  mender-connect is the device authorization status. Since only
+	  accepted devices can interact with the Mender Server, the
+	  Mender Client passes over DBus the authorization token which
+	  Mender Connect uses to establish a Websocket connection to the
+	  server.
