-## Start rpc service
-``` shell
+## Get data
+
+```shell
 sh get_data.sh
+```
+
+
+
+## RPC service
+
+### Start server
+
+``` shell
 python test_server.py uci_housing_model/
 ```
 
-## Prediction
+You can also start the default RPC service with the following line of code:
+
+```shell
+python -m paddle_serving_server.serve --model uci_housing_model --thread 10 --port 9393
+```
+
+### Client prediction
+
+The `paddlepaddle` package is used in `test_client.py`, and you may need to download the corresponding package(`pip install paddlepaddle`).
+
 ``` shell
 python test_client.py uci_housing_client/serving_client_conf.prototxt
 ```
 
-## prediction through http service
-Start a web service with default web service hosting modules
+
+
+## HTTP service
+
+### Start server
+
+Start a web service with default web service hosting modules:
 ``` shell
-python -m paddle_serving_server.web_serve --model uci_housing_model/ --thread 10 --name uci --port 9393 --name uci
+python -m paddle_serving_server.serve --model uci_housing_model --thread 10 --port 9393 --name uci
 ```
 
-## Prediction through http post
+### Client prediction
+
 ``` shell
 curl -H "Content-Type:application/json" -X POST -d '{"x": [0.0137, -0.1136, 0.2553, -0.0692, 0.0582, -0.0727, -0.1583, -0.0584, 0.6283, 0.4919, 0.1856, 0.0795, -0.0332], "fetch":["price"]}' http://127.0.0.1:9393/uci/prediction

-## 开启RPC服务端
-``` shell
+## 获取数据
+
+```shell
 sh get_data.sh
+```
+
+
+
+## RPC服务
+
+### 开启服务端
+
+``` shell
 python test_server.py uci_housing_model/
 ```
 
-## RPC预测
+也可以通过下面的一行代码开启默认RPC服务：
+
+```shell
+python -m paddle_serving_server.serve --model uci_housing_model --thread 10 --port 9393
+```
+
+### 客户端预测
+
+`test_client.py`中使用了`paddlepaddle`包，需要进行下载（`pip install paddlepaddle`）。
+
 ``` shell
 python test_client.py uci_housing_client/serving_client_conf.prototxt
 ```
 
-## 开启HTTP服务端
-Start a web service with default web service hosting modules
+
+
+## HTTP服务
+
+### 开启服务端
+
+通过下面的一行代码开启默认web服务：
+
 ``` shell
-python -m paddle_serving_server.web_serve --model uci_housing_model/ --thread 10 --name uci --port 9393 --name uci
+python -m paddle_serving_server.serve --model uci_housing_model --thread 10 --port 9393 --name uci
 ```
 
-## HTTP预测
+### 客户端预测
+
 ``` shell
 curl -H "Content-Type:application/json" -X POST -d '{"x": [0.0137, -0.1136, 0.2553, -0.0692, 0.0582, -0.0727, -0.1583, -0.0584, 0.6283, 0.4919, 0.1856, 0.0795, -0.0332], "fetch":["price"]}' http://127.0.0.1:9393/uci/prediction
