The Arch wiki has rapidly become my go-to source for every time I need a real answer... and honestly it should just become my default for everything Linux. It's astoundingly high quality, some of the best content out there whether or not you're using Arch.
So +1000, I love their work, and all the contributors! It's so, so good, and greatly appreciated.
A lot of pages are very bare or outdated, it should absolutely not be anything besides the default Arch wiki.
