+可以参见简单的教程：
+https://aistudio.baidu.com/aistudio/projectdetail/3986429
+
+这个 demo 是打车报销单的场景识别，定制化了地点。
+
+## 使用方法
+### 1. 配置环境
+请通过 setup_docker.sh 安装镜像。进入镜像后，安装tmux (apt-get install tmux)，方便后续演示。
+
+### 2. 演示
+* bash websocket_server.sh, 完成相关资源和库的下载。这时候服务已经启动。
+* 在镜像另一个终端中，bash websocket_client.sh， 通过client发送数据，得到结果。
