Sponsors

Does your company use Mocha? Ask your manager or marketing team if your company would be interested in supporting our project. Support will allow the maintainers to dedicate more time for maintenance and new features for everyone. Also, your company's logo will show on GitHub and on our site - who doesn't want a little extra exposure? Here's the info.

Development

You might want to know that:

• Mocha is one of the most-depended-upon modules on npm (source: libraries.io), and
• Mocha is an independent open-source project, maintained exclusively by volunteers.

You might want to help:

• New to contributing to Mocha? Check out this list of good first issues
• Mocha could use a hand with these issues
• The maintainer's handbook explains how things get done

Finally, come chat with the maintainers on Discord if you want to help with:

• Triaging issues, answering questions
• Review, merging, and closing pull requests
• Other project-maintenance-y things
