+## GRPC Health
+
+By default, the health endpoint will use the standard gRPC implementation for health, which does not integrate with Spring Boot Actuator.
+
+The server provides an optional integration with Actuator health information using the [gRPC Health API](https://grpc.io/docs/guides/health-checking/). 
+
+This integration enables the server to respond to gRPC health checks based on the `HealthEndpoint` from Actuator, which is the same used for the web version.
+
+To enable this integration, add the following properties to your application configuration:
+
+````properties
+grpc.server.health-service-type=ACTUATOR
+````
+
+The integration allows you to check the health status for the whole service or specific health indicators, where the `service` is the name of the healthindicator.
+`Watch` is not supported because actuator is pull-based and does not automatically tries to determine the status of the service to notify clients.
