Now you can go to your fork of the repository on GitHub and click on Pull Request to open a pull request. Make sure you tick off all the boxes on our checklist below. When you're ready, you can send your changes to the project maintainers for review.

It's ok if maintainers request changes, it happens to our core contributors
   too! So everyone can see the changes in the pull request, work in your local
   branch and push the changes to your fork. They will automatically appear in
   the pull request.
