Useful References for Understanding Nix/NixOS

I recently used Nix to configure my M2 Macbook Air, and manage all of my dotfiles. In the process I found a lot of useful references, detailing the ins and outs of Nix and NixOS.

I'm currently building out a similar solution for my homelab, and thought to document a list of useful references here.
