 * `t2-iso-gnome`
 
 It is reccommended to use `t2-iso-minimal` for installing NixOS. `t2-iso-gnome` can be used to preview what the system will look after the installation.
+
+You can build with this command:
+```
+nix build .#t2-iso-minimal
+```
+
+You need to have `nix` installed on a **Linux** host. If you are on macOS, you can use `podman` or `docker` with the `nixos/nix` image.
