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

    # add ags
    ags.url = "github:Aylur/ags";
  };

  outputs = { home-manager, nixpkgs, ... }@inputs:
  let
    username = "kahlenden";
    hostname = "Windows11";
    system = "x86_64-linux";
    pkgs = import nixpkgs {
      inherit system;
      config.allowUnfree = true;
    };
  in
  {
    nixosConfigurations.${hostname} = nixpkgs.lib.nixosSystem {
      specialArgs = { inherit inputs username system; };
      modules = [ ./configuration.nix
                  home-manager.nixosModules.home-manager {
                    home-manager.useGlobalPkgs = true;
                    home-manager.useUserPackages = true;
                    home-manager.users.${username} = import ./home.nix;
                    home-manager.extraSpecialArgs = {inherit inputs username; };
                  }
      ];
    };
  };
}

This is what i came up with, still error tho, no idea what went wrong
