+=== Adding user as admin

+. Log in to db01 server
+. Start the postgreSQL console
++
+``sudo -u postgres psql``
++
+. Connect to hyperkitty DB

+``\connect hyperkitty``
++
+. Add admin permissions to user

+== Deployment
+
+In case of new deployment of mailman in infrastructure, there are few tasks
+that need to be done manually.
+
+=== Migrating social accounts from OpenID Fedora to OpenIDC
+
+This needs to be done only once when you update from old OpenID Fedora auth provider
+to OpenIDC version. Doing this will correctly map the old accounts to new auth provider.
+
+. Log into mailman01
+. ``cd /srv/webui/bin/``
+. ``python migrate_fedora_auth.py``
++
+This script does nothing if the users were already migrated.
