+# Setting up Element Call (optional)
+
+The playbook can install and configure [Element Call](https://github.com/vector-im/element-call) for you.
+
+Element Call is a WebRTC-based video and voice calling platform that integrates with Matrix clients such as Element Web. It provides secure, decentralized communication with support for video calls, audio calls, and screen sharing.
+
+See the project's [documentation](https://github.com/vector-im/element-call) to learn more.
+
+## Decide on a domain and path
+
+By default, Element Call is configured to be served on the Matrix domain (`call.DOMAIN`, controlled by the `matrix_element_call_hostname` variable).
+
+This makes it easy to set it up, **without** having to adjust your DNS records manually.
+
+If you'd like to run Element Call on another hostname or path, use the `matrix_element_call_hostname` and `matrix_element_call_path_prefix` variables.
+
+## Adjusting DNS records
+
+If you've changed the default hostname, **you may need to adjust your DNS** records accordingly to point to the correct server.
+
+Ensure that the following DNS names have a public IP/FQDN:
+- `call.example.com`
+- `sfu.example.com`
+- `sfu-jwt.example.com`
+
+## Adjusting the playbook configuration
+
+NOTE: Element call is dependent on two other services for it to function as intended. In orter to utilise Element Call you need to also enable the [JWT Service](configuring-playbook-jwt-service.md) and [Livekit Server](configuring-playbook-livekit-server.md).
+
+
+Add the following configuration to your `inventory/host_vars/matrix.DOMAIN/vars.yml` file:
+
+```yaml
+matrix_element_call_enabled: true
+
+# Set a secure key for LiveKit authentication
+livekit_server_config_keys_devkey: 'your-secure-livekit-key'
+```
+
+## Installing
+
+After configuring the playbook and potentially [adjusting your DNS records](#adjusting-dns-records), run the [installation](installing.md) command: `just install-all` or `just setup-all`
+
+## Usage
+
+Once installed, Element Call integrates seamlessly with Matrix clients like Element Web. When the Element Call service is installed, the `/.well-known/matrix/client` file is also updated. A new `org.matrix.msc4143.rtc_foci` section is added to point to your JWT service URL (e.g., `https://sfu-jwt.example.com`).
+
+Additionally, the `/.well-known/element/element.json` file is created to help Element clients discover the Element Call URL (e.g., `https://call.example.com`).
+
+## Required Firewall and Port Forwarding Rules
+
+To ensure the services function correctly, the following firewall rules and port forwarding settings are required:
+
+LiveKit:
+
+	•	Forward UDP ports 50100:50200 to the Docker instance running LiveKit.
+	•	Forward TCP port 7881 to the Docker instance running LiveKit.
+
+Element Call:
+
+	•	Forward TCP port 443 to the server running Traefik (for Element Call).
+
+Ensure these ports are open and forwarded appropriately to allow traffic to flow correctly between the services.
+
+## Additional Information
+
+Refer to the Element Call documentation for more details on configuring and using Element Call.

+# Setting up JWT Service (optional)
+
+The playbook can install and configure [JWT Service](https://github.com/element-hq/lk-jwt-service) for you.
+
+LK-JWT-Service is currently used for a single reason: generate JWT tokens with a given identity for a given room, so that users can use them to authenticate against LiveKit SFU.
+
+See the project's [documentation](https://github.com/element-hq/lk-jwt-service/) to learn more.

+## Decide on a domain and path
+
+By default, JWT Service is configured to be served on the Matrix domain (`sfu-jwt.DOMAIN`, controlled by the `matrix_jwt-service_hostname` variable).
+
+This makes it easy to set it up, **without** having to adjust your DNS records manually.
+
+If you'd like to run JWT Service on another hostname or path, use the `matrix_jwt-service_hostname` variable.

+# Setting up LiveKit (optional)
+
+The playbook can install and configure [LiveKit](https://github.com/livekit/livekit) for you.
+
+LiveKit is an open source project that provides scalable, multi-user conferencing based on WebRTC. It's designed to provide everything you need to build real-time video audio data capabilities in your applications.
+
+See the project's [documentation](https://github.com/livekit/livekit) to learn more.
