I'd love NixOS more if they had any decent documentation.
Everything seems scattered around a dozen forums, a hundred old blog posts, and a thousand issues of "this work on my machine (3 releases ago)".
A lot of us use NixOS/nix yet haven't read any documentation nor hand-written nix ourself. That's Claude Code's job.
ChatGPT is very good at pulling it together to give you working code. Not on the first try, but on the third try it usually works.
It doesn't help that there are two NixOS wikis. nixos.wiki and wiki.nixos.org.
wiki.nixos.org claims that nixos.wiki is outdated and unofficial. But both appear to receive updates, and which one wins the SEO game is a coinflip whenever i google a nixos question.
