+To be a collaborator
+---
+
+When more than one person use a language which you can code (whether there are more than one person using a language can be judged according to the assessment of the issue).
+
+* Each person creates a package for himself to distinguish different people(if sub module has exists). Refer to `java-leetcode`. 
+For the first time, please submit by PR, you can obtain the permission of collaborator after this PR is merged.
+* Everyone creates a new one in their own package named `packageName.md`, add the index and then link it to the current sub module README.md, refer to `java-leetcode`.
+
+If there is no language in this repository. Please submit PR to create a new sub module like follow example. 
+Direct push is not allowed for create a new module. And you should support `GitHub action workflows` as much as possible. 
+
+this is a python sub module, if you want to create a new module that the language you use is not exists you should look at this structure.
+
+```
+python-leetcode
+    /laozhang   
+       /leetcode_12.py  
+       /laozhang.md
+    /dreamylost 
+       /leetcode_12.py
+       /dreamylost.md
+    README.md
+```
+
+edit `python-leetcode/README.md`, let's make `packageName.md` linked to `python-leetcode/README.md`, such as
+
+```
+[laozhang](./laozhang/laozhang.md)
+[dreamylost](./dreamylost/dreamylost.md)
+```
+
+## requirement
+
+* When non script language is used, it must be compiled locally. The JVM platform uses gradle spotlessApply to format the code, which is not required by script language
+* No code passed GitHub action workflow, please roll back immediately! (at present, this repository only supports checking JVM language and Rust)
+* If it doesn't pass sonarcloud, please roll back immediately!
+* If it fails to pass lgtm, please take time to solve it
+* Conflict resolution: only append is allowed, not delete
+* The copyright of the default java code is: all collaborator

+如何成为 Collaborator
+---
+
+[english](./CONTRIBUTING-en.md)
+
+多人同时使用一种语言时（是否存在多人使用一种语言，可根据 issue 的 assiginess 来判断）
+
+- 每个人为自己建一个package，用以区分不同人，参考 `java-leetcode`，第一次以PR形式提交，merge后你将获得Collaborator权限
+- 每个人在自己package中新建一个`packageName.md`，增加题目索引再链接到当前项目的README.md
+
+本库没有的语言，自己提PR新建子模块，参考`java-leetcode`新建模块，该操作不允许直接push，请尽可能的支持 `GitHub action workflows`（不会就忽略）
+
+如果你要创建新的语言的子模块，应该以下面的python-leetcode项目为例
+
+```
+python-leetcode
+    /laozhang             每个人的包
+       /leetcode_12.py    每个人刷的题，这里还能创建自己的子包，区分专题
+       /laozhang.md       每个人的题目索引
+    /dreamylost
+       /leetcode_12.py
+       /dreamylost.md
+    README.md             聚合每个人的.md文件
+```
+
+将`packageName.md`这么链接到python-leetcode的`README.md`中
+
+```
+[laozhang](./laozhang/laozhang.md)
+[dreamylost](./dreamylost/dreamylost.md)
+```
+
+## 要求
+
+* 使用非脚本语言时，必须本地编译通过，JVM平台统一使用 gradle spotlessApply 格式化代码，脚本语言不作要求
+* 没有通过GitHub action workflows的代码，请立刻回滚！（目前本库只支持对JVM语言和Rust的检查）
+* 没有通过sonarcloud的，请立刻回滚！
+* 没有通过lgtm的，请抽空解决即可
+* 解决冲突: 只允许 append 不能 delete
+* 默认Java代码的版权是: all Collaborator
