First, thank you for taking the time to contribute!
The following is a set of guidelines for contributors as well as information and instructions around our maintenance process. The two are closely tied together in terms of how we all work together and set expectations, so while you may not need to know everything in here to submit an issue or pull request, it's best to keep them in the same document.
Contributing isn't just writing code - it's anything that improves the project. All contributions are managed right here on GitHub. Here are some ways you can help:
If you're running into an issue, please take a look through existing issues and open a new one if needed. If you're able, include steps to reproduce, environment information, and screenshots/screencasts as relevant.
New features and enhancements are also managed via issues.
Pull requests represent a proposed solution to a specified problem. They should always reference an issue that describes the problem and contains discussion about the problem itself. Discussion on pull requests should be limited to the pull request itself, i.e. code review.

The develop branch is the development branch which means it contains the next version to be released. trunk contains the latest released version as reflected in the WordPress.org plugin repository. Always work on the develop branch and open up PRs against develop.
