-## Why my config don't work ?
+## How to feedback efficiently?
+
+Thank you for reporting an issue.
+
+1. It's RECOMMENDED to submit PR for typo or tiny bug fix.
+2. If this's a FEATURE request, please provide: details, pseudo codes if necessary.
+3. If this's a BUG, please provide: course repetition, error log and configuration. Fill in as much of the template below as you're able.
+4. **It will be nice to use `egg-init --type=simple bug` to provide a mini GitHub repository which can reproduce the issue.**
+
+Most importantly, please understand one thing: the relationship between the `user` and `the maintainer of open source project` is not `Buyer` and `Seller`, the issue is not a customer order either.
+When you're opening an issue, please hold a mentality of "working together to solve this problem." Do not expect us to serve you unilaterally.
+
+## Why my config don't work?
 
 Framework [Config](./basics/config.md) settings is powerfull, support different environments and different places(framework, plugins, app).

+## 如何高效的反馈问题？
+
+感谢您向我们反馈问题。
+
+1. 我们推荐如果是小问题（错别字修改，小的 bug fix）直接提交 PR。
+2. 如果是一个新需求，请提供：详细需求描述，最好是有伪代码示意。
+3. 如果是一个 BUG，请提供：复现步骤，错误日志以及相关配置，并尽量填写下面的模板中的条目。
+4. **如果可以，尽可能使用 `egg-init --type=simple bug` 提供一个最小可复现的代码仓库，方便我们排查问题。**
+5. 不要挤牙膏似的交流，扩展阅读：[如何向开源项目提交无法解答的问题](https://zhuanlan.zhihu.com/p/25795393)
+
+最重要的是，请明白一件事：开源项目的用户和维护者之间并不是甲方和乙方的关系，issue 也不是客服工单。在开 issue 的时候，请抱着一种『一起合作来解决这个问题』的心态，不要期待我们单方面地为你服务。

 ## 为什么我的配置不生效？
 
 框架的配置功能比较强大，有不同环境变量，又有框架、插件、应用等很多地方配置。
