NixOS is a very different type of Linux distribution. Everything can be controlled by one file.
The Configuration Unlike other distributions where you configure system wide programs with /etc and install programs with a package manage like APT, with NixOS EVERYTHING is done in /etc/nixos/configuration.nix or hardware specific configurations in /etc/nixos/hardware-configuration.nix
You can reference all my videos below and see my ending configuration files @ https://github.com/ChrisTitusTech/nixos-titus
A viewer of the channel also sent me this in-depth guide covering much more of NixOS including flakes and home manager. Here is that article: https://thiscute.world/en/posts/nixos-and-flake-basics - which is a great resource as well!
