+If server is started for the first time, database needs to be initialised and super-user created. Use the `init` command which will perform it automatically (the command generates password for the admin account):
+```shell
+$ docker exec merginmaps-server flask init
+```
+
+If you don't have `CONTACT_EMAIL` variable set, you will be asked to provide a super user email using the `-e`/`--email` option. The `init` will also check your server setup (celery jobs, emails, etc.) and print out a list of missing variables. If you see any errors in the console output, you can run the command again as the database and super user will not be re-initialised.

+:::tip
+If you want to create another users manually, you can use the following command:
 ```shell
-$ docker exec merginmaps-server flask init-db
 $ docker exec merginmaps-server flask user create <username> <password> --is-admin --email <email>
 ```
