+
+#### Configure a server name
+
+The configuration `server_name` sets the public-facing domain of the server and
+refers to [`server_name`](https://matrix-org.github.io/synapse/latest/usage/configuration/config_documentation.html#server_name) Synapse configuration.
+
+To change it to `tutorial-synapse.juju.local`, for example, run the following
+command:
+
+```
+juju config synapse server_name=tutorial-synapse.juju.local
+```
+
+#### Create a user
