What does this community need?

I've not set up a community before, i just want a place to discuss my hobbies. So if anyone has an idea of what needs to be added, i'm all ears.

My initial thoughts are that we probably want a wiki. Both as a quick reference and as a landing page for newbies. Yes, The Bad Site has one, but it's on fandom and i don't really feel like using it or straight up copying from it.
