  • One pull request per feature - If you want to do more than one thing, send multiple pull requests.

  • Add tests! - Your patch won't be accepted if it doesn’t have tests.

  • Document any change in behaviour - Make sure the README.md and CHANGELOG.md are kept up-to-date.

  • Consider our release cycle - We try to follow SemVer v2.0.0. Randomly breaking public APIs is not an option.

  • Send coherent history - Make sure each individual commit in your pull request is meaningful. If you had to make multiple intermediate commits while developing, please squash them before submitting.
