+
+`Zulip <https://zulip./>`__ is a team chat application.
+
+Unfortunately, Zulip does not yet listen to the Stackspin roles, so once you
+have installed Zulip, you need to make one of your users the owner. That allows
+this user to manage Zulip's settings from inside the application. This owner
+can also edit other users' roles.
+
+For this, you have to replace ``<your email>`` in the the following command and
+run it on your cluster:
+
+```
+kubectl exec -n stackspin-apps zulip-0 -c zulip -- sudo -u zulip /home/zulip/deployments/current/manage.py change_user_role <your email> owner --realm 2
+```
