 This will download three unitfiles:
 
 - ``funkwhale-server.service`` to launch the funkwhale web server
 - ``funkwhale-worker.service`` to launch the funkwhale task worker
+- ``funkwhale-beat.service`` to launch the funkwhale task beat (this is for recurring tasks)
 - ``funkwhale.target`` to easily stop and start all of the services at once
 
 You can of course review and edit them to suit your deployment scenario
