- Fork the Pillow repository.
- Create a branch from master.
- Develop bug fixes, features, tests, etc.
- Run the test suite on Python 2.7 and 3.x. You can enable [Travis CI](https://travis-ci.org/profile/) and [AppVeyor](https://ci.appveyor.com/projects/new) on your repo to catch test failures prior to the pull request, and [Codecov](https://codecov.io/gh) to see if the changed code is covered by tests.
- Run the test suite. You can enable [Travis CI](https://travis-ci.org/profile/) and [AppVeyor](https://ci.appveyor.com/projects/new) on your repo to catch test failures prior to the pull request, and [Codecov](https://codecov.io/gh) to see if the changed code is covered by tests.
- Create a pull request to pull the changes from your branch to the Pillow master.
### Guidelines
- Separate code commits from reformatting commits.
- Provide tests for any newly added code.
- Follow PEP8.
- Follow PEP 8.
- When committing only documentation changes please include [ci skip] in the commit message to avoid running tests on Travis-CI and AppVeyor.
