Apologies for the 'spam', but I was afraid editing my previous message would be in vain. If you desire/crave for decent documentation, then Bazzite deserves another endorsement. While its documentation isn't as expansive as the excellent ArchWiki, it should be more than able to answer your questions.

Secondly, if you happen to come across an issue that has been painstakingly difficult to resolve, then please consider consulting its many community channels for support. There's a Discourse, a Discord and an AnswerOverflow. So pick your poison 😉. FWIW, I've always had great experiences on their Discord.
