The following is a set of guidelines for contributing to Psalm, which is hosted in the Vimeo Organization on GitHub.
Make sure to check out the Contributing to Open Source on GitHub guide.
You can create an issue here, but before you do, follow these guidelines:
- Make sure that you are using the latest version (
master). - It’s by no means a requirement, but if it's a bug, and you provide demonstration code that can be pasted into https://psalm.dev, it will likely get fixed faster.
Have a look at the contributing documentation which is mirrored on Psalm’s website.
