 ### D-Bus API
 
-Cloud Hypervisor offers a D-Bus API as an alternative to its REST API. As of
-writing this document, the D-Bus API mirrors the functionality of the REST
-API and shares the same set of endpoints, meaning that it supports every call
-that is supported by the REST API and can be a drop-in replacement since it
-also consumes/produces JSON.
+Cloud Hypervisor offers a D-Bus API as an alternative to its REST API. This
+D-Bus API fully reflects the functionality of the REST API, exposing the

+
+In addition, the D-Bus API also exposes events from `event-monitor` in the
+form of a D-Bus signal to which users can subscribe. For more information,
