Add native Traefik support to Sygnal

 This optional playbook component is only useful to people who develop/build their own Matrix client applications themselves.
 
 
+## Decide on a domain and path
+
+By default, Sygnal is configured to use its own dedicated domain (`sygnal.DOMAIN`) and requires you to [adjust your DNS records](#adjusting-dns-records).
+
+You can override the domain and path like this:
+
+```yaml
+# Switch to the domain used for Matrix services (`matrix.DOMAIN`),
+# so we won't need to add additional DNS records for Sygnal.
+matrix_sygnal_hostname: "{{ matrix_server_fqn_matrix }}"
+
+# Expose under the /sygnal subpath
+matrix_sygnal_path_prefix: /sygnal
+```
+
+**NOTE**: When using `matrix-nginx-proxy` instead of Traefik, you won't be able to override the path prefix. You can only override the domain, but that needs to happen using another variable: `matrix_server_fqn_sygnal` (e.g. `matrix_server_fqn_sygnal: "push.{{ matrix_domain }}"`).
+
+
+## Adjusting DNS records
+
+Once you've decided on the domain and path, **you may need to adjust your DNS** records to point the Sygnal domain to the Matrix server.
+
+If you've decided to reuse the `matrix.` domain, you won't need to do any extra DNS configuration.

 ## Usage
 
-To make use of your Sygnal installation, you'd need to build your own Matrix client application, which uses the same API keys (for [GCM/FCM](https://firebase.google.com/docs/cloud-messaging/)) and certificates (for [APNS](https://developer.apple.com/notifications/)) and is also pointed to `https://sygnal.DOMAIN` as the configured push server.
