If you ask me youtube explanations by Hans Beekhuyzen are lots more appealing but reading line after line in a KB.
5 years ago I would also have said a propperly written KB is ideal. But I recently wanted to use docker on my synology and after having read more but half a bible without getting where I was wrong, I tried youtube (as my kids do). And after having watched 3-4 guidelines about docker I got it.
Conclusion? audio-visuals do win over textual information. I think roon should consider to do some short 1-2min example videos covering some aspects which are completely differnt to other software. This will get more important for future generations of users which are used to get information that way.
