+# Imagenet Pipeline WebService
+
+This document will takes Imagenet service as an example to introduce how to use Pipeline WebService.
+
+## Get model
+```
+sh get_model.sh
+python encrypt.py
+```
+
+## Start server
+
+```
+python -m paddle_serving_server.serve --model encrypt_server/ --port 9400  --encryption_rpc_port 9401  --use_encryption_model &
+python web_service.py &>log.txt &
+```
+
+## client test
+```
+python http_client.py
+```
+
+if you configure the api gateway, you can use `https_client.py`

+# Imagenet Pipeline WebService
+
+这里以 Imagenet 服务为例来介绍 Pipeline WebService 的使用。
+
+## 获取模型
+```
+sh get_model.sh
+python encrypt.py
+```
+
+## 启动服务
+
+```
+python -m paddle_serving_server.serve --model encrypt_server/ --port 9400  --encryption_rpc_port 9401  --use_encryption_model &
+python web_service.py &>log.txt &
+```
+
+## 测试
+```
+python http_client.py
+```
+如果您已经配置好了api gateway， 您可以使用 `https_client.py`
