Importing Modules {#sec-importing-modules}

Sometimes NixOS modules need to be used in configuration but exist outside of Nixpkgs. These modules can be imported:

{
  config,
  lib,
  pkgs,
  ...
}:

{
  imports = [
    # Use a locally-available module definition in
    # ./example-module/default.nix
    ./example-module
  ];

  services.exampleModule.enable = true;
}
