+# Non-Interactive Installation
+In order to install without interaction some environment variables need to be pre-set.

+## Environment Variables

+
+## Example Noninteractive Install
+This will perform a noninteractive install with the default environment variables set in `.install_barebones`.

 # Post-Installation
 When Mistborn-base starts up it will create volumes, initialize the PostgreSQL database, start pihole, run Django migrations and then check to see if a Mistborn superuser named `admin` exists yet. If not, it will create the superuser `admin` along with an accompanying default Wireguard configuration file and start the Wireguard service. You can watch all of this happen with:
 ```
