Our main goal is to build a healthy and sustainable community around Flipper, so we're open to any new ideas and contributions. We also have some rules and taboos here, so please read this page and our Code of Conduct carefully.
If you've found an issue and want to report it, please check our Issues page. Make sure the description contains information about the firmware version you're using, your platform, and a clear explanation of the steps to reproduce the issue.
Before opening a PR, please confirm that your changes must be contained in the firmware. Many ideas can easily be implemented as external applications and published in the Flipper Application Catalog (coming soon). If you are unsure, reach out to us on the Discord Server or the Issues page, and we'll help you find the right place for your code.
Finally, open a Pull Request and make sure that CI/CD statuses are all green.
