We ♥ contributors! By participating in this project, you agree to abide by the Ruby for Good code of conduct.

First: if you're unsure or afraid of anything, just ask or submit the issue or pull request anyways. You won't be yelled at for giving your best effort. The worst that can happen is that you'll be politely asked to change something. We appreciate any sort of contributions, and don't want a wall of rules to get in the way of that.

Here are the basic steps to submit a pull request. Make sure that you're working on an open issue–if the relevant issue doesn't exist, open it!

  1. Claim an issue on our issue tracker by assigning it to yourself (core team member) or commenting. If the issue doesn't exist yet, open it.

  2. Fork the repo.

  3. cd into the repo. Install the correct version of ruby if prompted. Install ImageMagick if you don't have it installed already: brew install imagemagick

  4. Run ./bin/setup.

  5. Run the tests. We only take pull requests with passing tests, and it's great to know that you have a clean slate: bundle exec rake

  6. Add a test for your change. If you are adding functionality or fixing a bug, you should add a test!

  7. Make the test pass.

  8. Push to your fork and submit a pull request. Include the issue number (ex. Resolves #1) in the PR description.

At this point you're waiting on us–we'll try to respond to your PR quickly. We may suggest some changes or improvements or alternatives.

Some things that will increase the chance that your pull request is accepted:

  • Use Rails idioms and helpers
  • Include tests that fail without your code, and pass with it
  • Update the documentation, the surrounding one, examples elsewhere, guides, whatever is affected by your contribution
