-## 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
 ```

+## RPC服务
+
+### 开启服务端
+
+``` shell

-## RPC预测
+也可以通过下面的一行代码开启默认RPC服务：

+
+### 客户端预测
+
+`test_client.py`中使用了`paddlepaddle`包，需要进行下载（`pip install paddlepaddle`）。
