Project Goals

Please keep these project goals in mind as you propose changes:

Fully support the [CommonMark spec] (100% compliance)
Provide an extensible parser/renderer which users may customize as needed
Continuously improve performance without sacrificing quality or compliance
Match the underlying logic of the official reference implementations of CommonMark

PSR-2 Coding Standard - The easiest way to apply the conventions is to install PHP Code Sniffer.
Add tests! - Your patch won't be accepted if it doesn't have tests.
Document any change in behaviour - Make sure the README.md and any other relevant documentation are kept up-to-date.
Consider our release cycle - We try to follow SemVer v2.0.0. Randomly breaking public APIs is not an option.
Create feature branches - Don't ask us to pull from your default branch.
One pull request per feature - If you want to do more than one thing, send multiple pull requests.
Send coherent history - Make sure each individual commit in your pull request is meaningful. If you had to make multiple intermediate commits while developing, please squash them before submitting.

$ composer test

Happy coding!
