-####8 Service Discovery support
+#### 8 Service Discovery support
 Instead of hard coding the server address in config file( or java source code), NettyRPC support service discovery. 
 All Services will automatically register themself to registry(Zookeeper) after services started,  and NettyRPC client will automatically query addresses from the registry.
 If you want to scale out and deploy more server, you just simply start the new services, NettyRPC client will automatically got notified and dispatch requests to that new services.
