 ### Command Line Using Gradle
 
+To start the gRPC server application using Spring Boot run the following:
+
     $ gradlew :grpc-server:bootRun
 
-This will start the gRPC server application using Spring Boot.
+To test the gRPC server application run the gRPC client sample using Spring Boot run as follows:
+    
+    $ gradlew :grpc-client:bootRun
