+		public interface HelloService { 
+			String hello(String name); 
+			String hello(Person person);
+		}
+
+2. Implement the interface with annotation @RpcService:
+
+		@RpcService(HelloService.class)
+		public class HelloServiceImpl implements HelloService {
+			@Override
+			public String hello(String name) {
+				return "Hello! " + name;
+			}
+
+			@Override
+			public String hello(Person person) {
+				return "Hello! " + person.getFirstName() + " " + person.getLastName();
+			}
+		}
+
+3. Run the server with zookeeper:
+
+		RpcBootstrap
 
+4. Run the client:
+ 
+		ServiceDiscovery serviceDiscovery = new ServiceDiscovery("127.0.0.1:2181");
+		final RpcClient rpcClient = new RpcClient(serviceDiscovery);
+		HelloService helloService = rpcClient.create(HelloService.class);
+		String result = helloService.hello("World");
