+#### Push Notifications
+
+You can designate generic worker to sending push notifications to
+a [push gateway](https://spec.matrix.org/v1.5/push-gateway-api/) such as
+[sygnal](https://github.com/matrix-org/sygnal) and email.
+
+This will stop the main process sending push notifications.
+
+The workers responsible for sending push notifications can be defined using the
+[`pusher_instances`](usage/configuration/config_documentation.md#pusher_instances)
+option. For example:
+
+```yaml
+pusher_instances:
+  - pusher_worker1
+  - pusher_worker2
+```
+
+Multiple workers can be added to this map, in which case the work is balanced
+across them. Ensure the main process and all pusher workers are restarted after changing
+this option.
+
+These workers don't need to accept incoming HTTP requests to send push notifications,
+so no additional reverse proxy configuration is required for pusher workers.
