+# Auxolotl System Template
+
+A (nearly) complete and ready-to-run NixOS template.
+
+## Getting Started
+
+1. Install a fresh copy of NixOS and boot into your new system.
+2. Run [command] to generate your system's `hardware-configuration.nix` file.
+3. Copy `hardware-configuration.nix` into the `hosts/myHost` folder.
+4. Edit the `hosts/myHost/configuration.nix` file to suit your needs. This file is fully documented with all of the different options available in this template.
+5. Run `nixos-rebuild boot --flake .` and restart.
+6. Enjoy your new NixOS system!
