Interestingly enough, the ArchWiki itself seems to slowly be getting augmented by NixOS its wiki. Due to the way NixOS works, new packages constantly hit weird edge cases, which then requires deep diving into the package to write a workaround, the info of which either ends up in the wiki or the .nix package comments.

Arch and its wikin were already pretty good when it happened, but the real turning point was when the Gentoo wiki got hacked. After that, it never really recovered, and the Arch wiki must have absorbed a lot of that expertise because that's when it really took off.

as I recall anyway. can't believe it's been so long.
