# NixOS module {#sec-flakes-nixos-module}
To use Home Manager as a NixOS module, a bare-minimum `flake.nix` would
be as follows:
``` nix
{
description = "NixOS configuration";
inputs = {
nixpkgs.url = "github:nixos/nixpkgs/nixos-unstable";
home-manager.url = "github:nix-community/home-manager";
home-manager.inputs.nixpkgs.follows = "nixpkgs";
};
outputs = inputs@{ nixpkgs, home-manager, ... }: {
nixosConfigurations = {
hostname = nixpkgs.lib.nixosSystem {
system = "x86_64-linux";
modules = [
./configuration.nix
home-manager.nixosModules.home-manager
{
home-manager.useGlobalPkgs = true;
home-manager.useUserPackages = true;
home-manager.users.jdoe = import ./home.nix;
# Optionally, use home-manager.extraSpecialArgs to pass
# arguments to home.nix
}
];
};
};
};
}
```
The Home Manager configuration is then part of the NixOS configuration
and is automatically rebuilt with the system when using the appropriate
command for the system, such as
`nixos-rebuild switch --flake <flake-uri>`.
You can use the above `flake.nix` as a template in `/etc/nixos` by
``` shell
$ nix flake new /etc/nixos -t github:nix-community/home-manager#nixos
```
