+## how to use nix-helper
+
+The tool nix-helper is installed by this configuration. It simplifies administrating nixos and adds more output to the rebuild command. It also features a diff after a successful build. The command uses the `NH_FLAKE` environment variable to be able to run from whatever directory.
+
+Basic commands with a set `NH_FLAKE` variable are:
+
+```bash
+$ nh os switch
+$ nh os build
+$ nh os test
+$ nh clean all --keep 5
+```
+
+There is also the option to interface with home-manager by using `nh home switch`but this isn't necessary since home-manager is imported as a module in this config.
