+## Notes
+
+This chart will only deploy the body-based router deployment and service.
+Note that this should only be deployed once per Gateway.
+
+Additional configuration is needed to configure a proxy extension that calls
+out to the service in the request path. For example, vwith Envoy Gateway, this
+would require configuring EnvoyExtensionPolicy.
