 ## 2) Switch to it

 ## Updating later
 
 - If you keep `nanuqsaurus.url` pointing at the repo, you can update with:
   - `nix flake update` (in `/etc/nixos`), then
-  - `sudo nixos-rebuild switch --flake /etc/nixos#my-host`
+  - `sudo nixos-rebuild switch --flake /etc/nixos#nanuqsaurus`
 
 - Keep all your machine-specific changes in the wrapper flake (additional modules, packages, services, etc.).
