I don't use Arch anymore, yet I still find myself reading their wiki from time to time. It's a phenomenal resource.

I don't even use Arch, but I agree that their Wiki is awesome. Unless my problem is super obscure (and sometimes even then), I can nearly always find an answer there. But the best part is that it seems to be never incorrect, unlike essentially every other result in Google.

I also find myself using https://man.archlinux.org/ a lot. It's much more readable/user-friendly than https://man7.org plus it contains man-pages from their `extra` repo which contains a lot of popular oss tooling.
