+# Contribution Guide
+
+If you have any comment or advice, please report your [issue](https://github.com/antvis/g2/issues),
+or make any change as you wish and submit an [PR](https://github.com/antvis/g2/pulls).
+
+## Reporting New Issues
+
+- Please specify what kind of issue it is.
+- Before you report an issue, please search for related issues. Make sure you are not going to open a duplicate issue.
+- Explain your purpose clearly in tags(see **Useful Tags**), title, or content.
+
+AntV group members will confirm the purpose of the issue, replace more accurate tags for it, identify related milestone, and assign developers working on it.
+
+## Submitting Code
+
+### Pull Request Guide
+
+If you are developer of AntV repo and you are willing to contribute, feel free to create a new branch, finish your modification and submit a PR. AntV group will review your work and merge it to master branch.
+
+```bash
+# Create a new branch for development. The name of branch should be semantic, avoiding words like 'update' or 'tmp'. We suggest to use feature/xxx, if the modification is about to implement a new feature.
+$ git checkout -b branch-name
+
+# Run the test after you finish your modification. Add new test cases or change old ones if you feel necessary
+$ npm test
+
+# If your modification pass the tests, congradulations it's time to push your work back to us. Notice that the commit message should be wirtten in the following format.
+$ git add . # git add -u to delete files
+$ git commit -m "fix(role): role.use must xxx"
+$ git push origin branch-name
+```
+
+Then you can create a Pull Request at [g2](https://github.com/antvis/g2/pulls).
+
+No one can guarantee how much will be remembered about certain PR after some time. To make sure we can easily recap what happened previously, please provide the following information in your PR.
+
+1. Need: What function you want to achieve (Generally, please point out which issue is related).
+2. Updating Reason: Different with issue. Briefly describe your reason and logic about why you need to make such modification.
+3. Related Testing: Briefly describe what part of testing is relevant to your modification.
+4. User Tips: Notice for g2 users. You can skip this part, if the PR is not about update in API or potential compatibility problem.
+
+### Style Guide
+
+Eslint can help to identify styling issues that may exist in your code. Your code is required to pass the test from eslint. Run the test locally by `$ npm run lint`.
+
+### Commit Message Format
+
+You are encouraged to use [angular commit-message-format](https://github.com/angular/angular.js/blob/master/CONTRIBUTING.md#commit-message-format) to write commit message. In this way, we could have a more trackable history and an automatically generated changelog.
+
+```xml
+<type>(<scope>): <subject>
+<BLANK LINE>
+<body>
+<BLANK LINE>
+<footer>
+```
+
+（1）type
+
+Must be one of the following:
+
+- feat: A new feature
+- fix: A bug fix
+- docs: Documentation-only changes
+- style: Changes that do not affect the meaning of the code (white-space, formatting, missing semi-colons, etc)
+- refactor: A code change that neither fixes a bug nor adds a feature
+- perf: A code change that improves performance
+- test: Adding missing tests
+- chore: Changes to the build process or auxiliary tools and libraries such as documentation generation
+- deps: Updates about dependencies
+
+（2）scope
+
+The scope could be anything specifying place of the commit change.
+
+（3）subject
+
+Use succinct words to describe what did you do in the commit change.
+
+（4）body
+
+Feel free to add more content in the body, if you think subject is not self-explanatory enough, such as what it is the purpose or reasons of you commit.
+
+（5）footer
+
+- **If the commit is a Breaking Change, please note it clearly in this part.**
+- related issues, like `Closes #1, Closes #2, #3`
+
+e.g.
+
+```
+fix($compile): [BREAKING_CHANGE] couple of unit tests for IE9
+
+Older IEs serialize html uppercased, but IE9 does not...
+Would be better to expect case insensitive, unfortunately jasmine does
+not allow to user regexps for throw expectations.
+
+Document change on antvis/g2#123
+
+Closes #392
+
+BREAKING CHANGE:
+
+  Breaks foo.bar api, foo.baz should be used instead
+```
+
+Look at [these files](https://docs.google.com/document/d/1QrDFcIiPjSLDn3EL15IJygNPiHORgU1_OOAqWjiDU5Y/edit) for more details.
+
+## Release
+
+g2 uses semantic versioning in release process based on [semver].
+
+### Branch Strategy
+
+`master` branch is the latest stable version. 
+
+- just checkout develop branch from `master`
+- All new features will be added into `master` or `next` branch as well as all bug-fix except security issues. In such way, we can motivate developers to update to the latest stable version.
+
+
+### Release Strategy
+
+In the release of every stable version, there will be a PM who has the following responsibilities in different stages of the release.
+
+#### Preparation
+
+- Set up milestone. Confirm that request is related to milestone.
+
+#### Before Release
+
+- Confirm that performance test is passed and all issues in current Milestone are either closed or can be delayed to later versions.
+- Open a new [Release Proposal MR], and write `History` as [node CHANGELOG]. Don't forget to correct content in documentation which is related to the releasing version. Commits can be generated automatically.
+    ```
+    $ npm run commits
+    ```
+- Nominate PM for next stable version.

+# 代码贡献规范
+
+有任何疑问，欢迎提交 [issue](https://github.com/antvis/g2/issues)，
+或者直接修改提交 [PR](https://github.com/antvis/g2/pulls)!
+
+## 提交 issue
+
+- 请确定 issue 的类型。
+- 请避免提交重复的 issue，在提交之前搜索现有的 issue。
+- 在标签(分类参考**标签分类**), 标题 或者内容中体现明确的意图。
+
+随后 AntV 负责人会确认 issue 意图，更新合适的标签，关联 milestone，指派开发者。
+
+## 提交代码
+
+### 提交 Pull Request
+
+如果你有仓库的开发者权限，而且希望贡献代码，那么你可以创建分支修改代码提交 PR，AntV 开发团队会 review 代码合并到主干。
+
+```bash
+# 先创建开发分支开发，分支名应该有含义，避免使用 update、tmp 之类的
+$ git checkout -b branch-name
+
+# 开发完成后跑下测试是否通过，必要时需要新增或修改测试用例
+$ npm test
+
+# 测试通过后，提交代码，message 见下面的规范
+
+$ git add . # git add -u 删除文件
+$ git commit -m "fix(role): role.use must xxx"
+$ git push origin branch-name
+```
+
+提交后就可以在 [g2](https://github.com/antvis/g2/pulls) 创建 Pull Request 了。
+
+由于谁也无法保证过了多久之后还记得多少，为了后期回溯历史的方便，请在提交 MR 时确保提供了以下信息。
+
+1. 需求点（一般关联 issue 或者注释都算）
+2. 升级原因（不同于 issue，可以简要描述下为什么要处理）
+3. 框架测试点（可以关联到测试文件，不用详细描述，关键点即可）
+4. 关注点（针对用户而言，可以没有，一般是不兼容更新等，需要额外提示）
+
+### 代码风格
+
+你的代码风格必须通过 eslint，你可以运行 `$ npm run lint` 本地测试。
+
+### Commit 提交规范
+
+根据 [angular 规范](https://github.com/angular/angular.js/blob/master/CONTRIBUTING.md#commit-message-format)提交 commit，
+这样 history 看起来更加清晰，还可以自动生成 changelog。
+
+```xml
+<type>(<scope>): <subject>
+<BLANK LINE>
+<body>
+<BLANK LINE>
+<footer>
+```
+
+（1）type
+
+提交 commit 的类型，包括以下几种
+
+- feat: 新功能
+- fix: 修复问题
+- docs: 修改文档
+- style: 修改代码格式，不影响代码逻辑
+- refactor: 重构代码，理论上不影响现有功能
+- perf: 提升性能
+- test: 增加修改测试用例
+- chore: 修改工具相关（包括但不限于文档、代码生成等）
+- deps: 升级依赖
+
+（2）scope
+
+修改文件的范围
+
+（3）subject
+
+用一句话清楚的描述这次提交做了什么
+
+（4）body
+
+补充 subject，适当增加原因、目的等相关因素，也可不写。
+
+（5）footer
+
+- **当有非兼容修改(Breaking Change)时必须在这里描述清楚**
+- 关联相关 issue，如 `Closes #1, Closes #2, #3`
+
+示例
+
+```
+fix($compile): [BREAKING_CHANGE] couple of unit tests for IE9
+
+Older IEs serialize html uppercased, but IE9 does not...

+not allow to user regexps for throw expectations.

+
+## 发布管理
+
+g2 基于 [semver] 语义化版本号进行发布。
+
+`master` 分支为当前稳定发布的版本。
+
+- 直接从 `master` 切出开发分支
+- 所有 API 的废弃都需要在当前的稳定版本上 `deprecate` 提示，并保证在当前的稳定版本上一直兼容到新版本的发布。
+
+### 发布策略
+
+每个大版本都有一个发布经理管理（PM），他/她要做的事情
+
+#### 准备工作：
+
+- 建立 milestone，确认需求关联 milestone，指派和更新 issues。
+
+#### 发布前：
+
+- 确认当前 Milestone 所有的 issue 都已关闭或可延期，完成性能测试。
+- 发起一个新的 [Release Proposal MR]，按照 [node CHANGELOG] 进行 `History` 的编写，修正文档中与版本相关的内容，commits 可以自动生成。
+    ```bash
+    $ npm run commits
+    ```
+- 指定下一个大版本的 PM。
+
+#### 发布时：
+
+- 将老的稳定版本（master）备份到以当前大版本为名字的分支上（例如 `1.x`），并设置 tag 为 {v}.x`（ v 为当前版本，例如 `1.x`）。
+- 发布新的稳定版本到 [npm]，并通知上层框架进行更新。
+- `npm publish` 之前，请先阅读[『我是如何发布一个 npm 包的』]。
