How to Contribute Code

Before you get started writing code, be sure what you plan to work on is something we'll be able to accept. The easiest way is to look through out list of good first issues and find something that sounds interesting.

If there's something else you'd like to work on, just add a comment in the relevant issue and we'll be happy to discuss your plans. If you have an idea that doesn't have an issue at all, be sure to file an issue first.

Once you have a patch ready:

  • Make sure all tests are passing and try to add tests for the code you've written. You can run tests in XCode by selecting the uispecs target and hitting CMD-U.
  • Submit a pull request! From there, we'll guide you through the review process to the eventual landing of your code. We aim to respond to all review requests within two business days.
