You can use the self-hosted Jitsi server through Riot, through an Integration Manager like [Dimension](docs/configuring-playbook-dimension.md) or directly at `https://jitsi.DOMAIN`.
To use it via riot-web, make sure you've installed the `develop` version and fully reloaded your riot-web page (at `riot.DOMAIN`). Starting a video-conference in a room containing more than 2 members should then create a Jitsi widget which utilizes your self-hosted Jitsi server.
