🚀 Installation

Add it to your flake.nix inputs:

nixkit = {
    url = "github:frostplexx/nixkit";
    # or for local development:
    # url = "path:/path/to/nixkit";
};

Add the home manager module:

home-manager = {
    sharedModules = [
        inputs.nixkit.homeModules.default
    ];
};

Add the nix module:

On NixOS:

modules = [
    inputs.nixkit.nixosModules.default
];

On macOS:

modules = [
    inputs.nixkit.darwinModules.default
];

Using the Overlay

{
  nixpkgs.overlays = [ nixkit.overlays.default ];

  # Now packages are available as pkgs.opsops, pkgs.ndcli, etc.
  environment.systemPackages = with pkgs; [
    opsops
    ndcli
  ];
}

Direct Package Installation

# Install individual packages
nix profile install github:frostplexx/nixkit#opsops
nix profile install github:frostplexx/nixkit#ndcli

# Or run directly
nix run github:frostplexx/nixkit#opsops

🔧 Module Configuration

Home Manager Modules
