# Setting up LiveKit JWT Service (optional) The playbook can install and configure [LiveKit JWT Service](https://github.com/element-hq/lk-jwt-service/) for you. This is a helper component that allows [Element Call](configuring-playbook-element-call.md) to integrate with [LiveKit Server](configuring-playbook-livekit-server.md). 💡 LiveKit JWT Service is automatically installed and configured when [Element Call](configuring-playbook-element-call.md) is enabled, so you don't need to do anything extra. Take a look at: - `roles/custom/matrix-livekit-jwt-service/defaults/main.yml` for some variables that you can customize via your `vars.yml` file - `roles/custom/matrix-livekit-jwt-service/templates/env.j2` for the component's default configuration.
