I should add, to be fair to NixOS and the team, that there are three main official documenation sections: Nix, nixpkgs, and NixOS:

https://nixos.org/manual/nix/stable/

https://nixos.org/manual/nixpkgs/stable/

https://nixos.org/manual/nixos/stable/

Anyone looking into transitioning to NixOS should take a leisurely weekend and just read through all three of those first. Being at least familiar with all of what's there will make getting up and running a lot smoother.
