+# Spring Boot Example with gRPC
+
+### Introduction
+
+This example demonstrates how you can use Camel-gRPC Starter component. The example is composed of a standalone gRPC server and a Camel Spring-boot gRPC route acting as client.
+
+### Server
+
+You can build the server under the directory hello-camel-grpc-server with:
+
+ $ mvn clean install
+
+and then run the server with
+
+ $ mvn exec:java
+
+You should see the following output:
+
+[source,bash]
+----
+Aug 08, 2017 8:00:00 AM org.apache.camel.examples.grpc.HelloCamelServer start
+INFO: Server started. I'm listening on 50051
+----
+
+### Run the client
+
+You can build the client example under the directory hello-camel-grpc-client with:
+
+ $ mvn clean install
+
+and then run the example with
+
+ $ mvn spring-boot:run
+
+And you should see this output in the console.
+
+[source,bash]
