To create a new home, add a new directory to your homes directory.

# Create a directory in the `homes` directory for a new home. This should follow
# Snowfall Lib's required home target format to ensure that the correct architecture
# and output are used.
mkdir -p ./homes/x86_64-linux/user@my-home

Now create the Nix file for the home at homes/x86_64-linux/user@my-home/default.nix.

    # Snowfall Lib provides a customized `lib` instance with access to your flake's library
    # as well as the libraries available from your flake's inputs.
    # An instance of `pkgs` with your overlays and packages applied is also available.
    # You also have access to your flake's inputs.

    # Additional metadata is provided by Snowfall Lib.
    home, # The home architecture for this host (eg. `x86_64-linux`).
    target, # The Snowfall Lib target for this home (eg. `x86_64-home`).
    format, # A normalized name for the home target (eg. `home`).
    virtual, # A boolean to determine whether this home is a virtual target using nixos-generators.
    host, # The host name for this home.

    # All other arguments come from the home home.
    # Your configuration.

This home will be made available on your flakeā€™s homeConfigurations output with the same name as the directory that you created.

Homes can have additional specialArgs and modules configured within your call to mkFlake. See the following for an example which adds a Home Manager module to a specific host and sets a custom value in specialArgs.

	description = "My Flake";

	inputs = {
		nixpkgs.url = "github:nixos/nixpkgs/nixos-23.05";

		snowfall-lib = {
			url = "github:snowfallorg/lib";
			inputs.nixpkgs.follows = "nixpkgs";

	outputs = inputs:
        inputs.snowfall-lib.mkFlake {
            inherit inputs;
            src = ./.;

            # Add modules to all homes.
            homes.modules = with inputs; [

            # Add modules to a specific home.
            homes.users."my-user@my-host".modules = with inputs; [

            # Add modules to a specific home.
            homes.users."my-user@my-host".specialArgs = {
                my-custom-value = "my-value";
