 ### HTTP service
 
+Paddle Serving provides a built-in python module called `paddle_serving_server.serve` that can start a rpc service or a http service with one-line command. If we specify the argument `--name uci`, it means that we will have a HTTP service with a url of `$IP:$PORT/uci/prediction`
 ``` shell
-python -m paddle_serving_server.web_serve --model uci_housing_model --thread 10 --port 9292 --name uci
+python -m paddle_serving_server.serve --model uci_housing_model --thread 10 --port 9292 --name uci

+Here, we use curl to send a HTTP POST request to the service we just started. Users can use any python library to send HTTP POST as well, e.g, [requests](https://requests.readthedocs.io/en/master/).

 ### RPC service
 
+A user can also start a rpc service with `paddle_serving_server.serve`. RPC service is usually faster than HTTP service, although a user needs to do some coding based on Paddle Serving's python client API. Note that we do not specify `--name` here.
