+## Building a LiveCD
+
+To build a livecd using this flake, you can use the following command:
+
+```bash
+nix build .#nixosConfigurations.<your-configuration>.config.system.build.isoImage
+```
+
+Replace `<your-configuration>` with the name of your configuration (for example, `athame` or `metatron`). This will create an ISO image that you can burn to a CD or write to a USB stick.
+
+Please note that the resulting livecd will be a minimal system with the same packages and configuration as your system, but without any user data. It can be used for installation or recovery purposes.
