Contributor welcome notes

Thanks for contributing to Prawn!

You're now able to commit directly to our repositories, but please keep the following guidelines in mind:

• Every incoming pull request still needs to be reviewed from one of Prawn's maintainers(*), but contributors can help with the testing, tweaking, and merging of those requests as long as someone on core has signed off on the work.

• Contributors can create their own feature branches directly on the Prawn repository, which will make it easier for other contributors and core team members to make revisions to a pull request.

• Contributors can revert any code that gets put into master that is clearly broken in some way.

• Contributors can directly merge fixes for any bugs that have a clear cause and an obvious solution.

• Contributors can freely merge documentation improvements and other kinds of "safe changes" that wouldn't require much discussion.

• Core team members will still be responsible for release management and also for making final decisions on things, but contributors can take a more active role in those discussions and help out in a supporting role as much as they'd like.

• If in doubt about any of this, just ask us! These are not commandments, but instead just guidelines to keep us organized. We can tweak them over time.
