I'm writing a book about NixOS, you may track the progress here: https://drakerossman.com/blog/practical-nixos-the-book

It's more NixOS oriented, but most of the knowledge is obviously transferable to a bare-bones (if one could say that) Nix installation on top of other OSes.

With regards to all the Nix/NixOS documentation already out there, I'm trying to keep my stuff extremely straight-forward and rather simplistic (but not superficial), so the people outside of Nix (and even outside of Linux) may give it a solid try.

Just to note, if you wish to subscribe to the newsletter, it's broken now, gonna fix it in a few days.

Also a question to @grhmc: would you maybe have some doc that describes how to UN_install nix via your installer on macOS?
