+## 本地运行
+
+```sh
+$ git clone https://github.com/sinacloud/python-getting-started-dockerfile.git
+$ cd python-getting-started-dockerfile
+$ python main.py
+```
+

+
+## 部署到sinacloud
+
+首先，提交代码到你的sinacloud应用的git仓库。
+
+登陆sinacloud容器云的管理页面，在运行环境管理-代码管理-如何部署查看部署代码方式。
+
+部署完成之后，你就可以通过 http://$APPNAME.saelinzi.com 来访问你的应用了。
+```
+如果您的应用显示未激活，您需要设置host才能访问，设置方法参见应用的管理页面
+```
