# Example NixOS configuration using ngit-grasp module
# 
# Usage:
#   1. Add to your server's flake.nix inputs:
#      inputs.ngit-grasp.url = "github:DanConwayDev/ngit-grasp";
#
#   2. Import the module in your configuration:
#      imports = [ inputs.ngit-grasp.nixosModules.default ];
#
#   3. Configure the service (example below)

{ inputs, ... }:
