Befor adding that. Can you write a quick guide in discussions and link to it in the json? Like "After install config: Link"

This should not be a full guide, more like what can and should you configure for a minimal viable experiance.

Alright, i've made a short guide where everything is located and how its configured.
Problem with this application is that its the user who needs to setup all the important bits. We can't really force a specific set of configuration parameters because it will not work for them, maybe.
