Ternix turns clicks into a real flake.nix. These guides cover what to do with it next. You can apply it to a machine, change it by hand, and understand the flake model it is built on. If Nix is new to you, read Getting started, then the Nix language primer, then Flakes, before applying a config. If you already run NixOS, jump straight to Using a config or Editing.
