# flake-parts module {#sec-flakes-flake-parts-module}

When using [flake-parts](https://flake.parts)
you may wish to import Home Manager's flake module,
`flakeModules.home-manager`.

``` nix
{
  description = "flake-parts configuration";

  inputs = {
    nixpkgs.url = "github:nixos/nixpkgs/nixos-unstable";
    home-manager.url = "github:nix-community/home-manager";
    home-manager.inputs.nixpkgs.follows = "nixpkgs";
    flake-parts.url = "github:hercules-ci/flake-parts";
  };

  outputs = inputs@{ flake-parts, ... }:
    flake-parts.lib.mkFlake { inherit inputs; } {
      imports = [
        # Import home-manager's flake module
        inputs.home-manager.flakeModules.home-manager
      ];
      flake = {
        # Define `homeManagerModules`, `homeConfigurations`,
        # `nixosConfigurations`, etc here
      };
      # See flake.parts for more features, such as `perSystem`
    };
}
```

The flake module defines the `flake.homeManagerModules` and `flake.homeConfigurations`
options, allowing them to be properly merged if they are defined in multiple
modules.

If you are only defining `homeManagerModules` and/or `homeConfigurations` once in a
single module, flake-parts should work fine without importing
`flakeModules.home-manager`.
