+This example shows how to use server_utility plugin to send status messages.
+
+The messages will appear in GCS log. In order to debug messages you can use:
+  - QGroundControll MAVLink Inspector
+  - Wireshark (https://mavlink.io/en/guide/wireshark.html)
+
+In this example we are changing sysid in order to show our message along the
+other messages in QGroundControll interface.
