+### Get Sample Dataset
 
-### 获取样例数据
 ```
 sh get_data.sh
 ```
 
-### 保存模型和配置文件
+### Train and Save Model
 ```
 python local_train.py
 ```
-执行脚本后会在当前目录生成ctr_server_model和ctr_client_config文件夹,以及ctr_server_model_kv, ctr_client_conf_kv。
+the trained model will be in ./ctr_server_model and ./ctr_client_config, and ctr_server_model_kv, ctr_client_conf_kv。
 
-### 启动稀疏参数服务器
+### Start Sparse Parameter Server
 ```
 cp ../../../build_server/core/predictor/seq_generator seq_generator
 cp ../../../build_server/output/bin/cube* ./cube/
 sh cube_prepare.sh &
 ```
 
-此处，模型当中的稀疏参数会被存放在稀疏参数服务器Cube当中，关于稀疏参数服务器Cube的介绍，请阅读[单机版稀疏参数服务器Cube](../../../doc/CUBE_LOCAL_CN.md)
+Here, the sparse parameter is loaded by cube sparse parameter server，for more details please read [Cube: Sparse Parameter Server (Local Mode)](../../../doc/CUBE_LOCAL.md)
 
-### 启动RPC预测服务，服务端线程数为4（可在test_server.py配置）
+### Start RPC Predictor, the number of serving thread is 4（configurable in test_server.py）
 
 ```
 python test_server.py ctr_serving_model_kv 
 ```
 
-### 执行预测
+### Run Prediction
