+## Jitsi domain
+
+By default dimension will use [jitsi.riot.im](https://jitsi.riot.im/) as the `conferenceDomain` of Jitsi widgets. For users running a self-hosted jitsi instance, you will likely want the widget to use your Jitsi instance. Currently there is no way to configure this via the playbook, see [this issue](https://github.com/turt2live/matrix-dimension/issues/345) for details.
+
+In the interim until the above limitation is resolved, an admin user needs to configure the domain via the admin ui once dimension is running. In riot-web, go to *Manage Integrations* → *Settings* → *Widgets* → *Jitsi Conference Settings* and set *Jitsi Domain* and *Jitsi Script URL* appropriately.

 ## Additional features
 
 To use a more custom configuration, you can define a `matrix_dimension_configuration_extension_yaml` string variable and put your configuration in it.
