The following is a set of guidelines for contributing to Ant Design. Please spend several minutes reading these guidelines before you create an issue or pull request.
We have adopted a [Code of Conduct](https://github.com/ant-design/ant-design/blob/master/CODE_OF_CONDUCT.md) that we expect project participants to adhere to. Please read the full text so that you can understand what actions will and will not be tolerated.
## Open Development
All work on Ant Design happens directly on [GitHub](https://github.com/ant-design). Both core team members and external contributors send pull requests which go through the same review process.
According to our [release schedule](changelog#Release-Schedule), we maintain two branches, `master` and `feature`. If you send a bugfix pull request, please do it against the `master` branch, if it's a feature pull request, please do it against the `feature` branch.
We are using [GitHub Issues](https://github.com/ant-design/ant-design/issues) for bug tracking. The best way to get your bug fixed is using our [issue helper](http://new-issue.ant.design) and provide reproduction steps with this [template](https://u.ant.design/codesandbox-repro).
If you intend to change the public API or introduce new feature, we also recommend you use our [issue helper](http://new-issue.ant.design) to create a feature request issue.
Working on your first Pull Request? You can learn how from this free video series:
[How to Contribute to an Open Source Project on GitHub](https://egghead.io/courses/how-to-contribute-to-an-open-source-project-on-github)
To help you get your feet wet and get you familiar with our contribution process, we have a list of [good first issues](https://github.com/ant-design/ant-design/issues?q=is%3Aissue+is%3Aopen+label%3A%22good+first+issue%22) that contain bugs or small features that have a relatively limited scope. This is a great place to get started.
If you decide to fix an issue, please be sure to check the comment thread in case somebody is already working on a fix. If nobody is working on it at the moment, please leave a comment stating that you intend to work on it so other people don't accidentally duplicate your effort.
The core team is monitoring for pull requests. We will review your pull request and either merge it, request changes to it, or close it with an explanation.
**Before submitting a pull request**, please make sure the following is done:
1. Run `npm test -- -u` to update the [jest snapshots](http://facebook.github.io/jest/docs/en/snapshot-testing.html#snapshot-testing-with-jest) and commit these changes as well (if there are any updates).
1. Make sure your code lints (npm run lint). Tip: Lint runs automatically when you `git commit` (Use [Git Hooks](https://git-scm.com/book/en/v2/Customizing-Git-Git-Hooks)).
Since antd's components are based on react-component, sometimes you may need to send pull request to the corresponding react-component repository. If it's a bugfix pull request, after it's merged, the core team will release a patch release for that component as soon as possible, then you only need to reinstall antd in your project to get the latest patch release. If it's a feature pull request, after it's merged, the core team will release a minor release, then you need raise another pull request to [Ant Design](https://github.com/ant-design/ant-design/) to update dependencies, document and TypeScript interfaces (if needed).
