 To have the account created automatically, you just need to define a few environment variables:
 
+- ``INITIAL_ADMIN_ACCOUNT``: the admin username: The first part of the e-mail address before the @.
+- ``INITIAL_ADMIN_DOMAIN``: the domain appendix: Most probably identical to the ``DOMAIN`` variable.
+- ``INITIAL_ADMIN_PW``: the admin password.
+- ``INITIAL_ADMIN_MODE``: one of the options below how the code should behave when it will try to create the admin user:
+  
+  - ``create``: (default) Will try to create user and will raise an exception if present.
+  - ``ifmissing``: if user exists, nothing happens, else it will be created.

 Depending on your particular deployment you most probably will want to change the default.
