AppDaemon dashboard - get it up and running

So I thought I would give it a try to get AppDaemon Dashboard up and running. Not the easiest thing for a newbie for sure!

I have Appdeamon installed and the confoguration file according to the instruction (http://appdaemon.readthedocs.io/en/stable/DASHBOARD_INSTALL.html).
Now I have come to the point where I am suppose to restart AppDaemon. How do I do that from the terminal? I cannot find the right command for this…
Thanks for the help!

sudo systemctl restart appdaemon@homeassistant should do the trick…
