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 ourCode of Conduct carefully.

The best place to search for answers is ourUser Documentation. If you can't find the answer there, check ourDiscord Server or ourForum. If you want to contribute to the firmware development or modify it for your own needs, you can also check ourDeveloper Documentation.

If you've found an issue and want to report it, please check ourIssues 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 theFlipper Application Catalog. If you are unsure, reach out to us on theDiscord Server or theIssues page, and we'll help you find the right place for your code.

Also, please read ourContribution Guide and ourCoding Style, and make sure your code is compatible with ourProject License.

Finally, open aPull Request and make sure that CI/CD statuses are all green.

Flipper Zero Firmware is written in C, with some bits and pieces written in C++ and armv7m assembly languages. An intermediate level of C knowledge is recommended for comfortable programming. C, C++, and armv7m assembly languages are supported for Flipper applications.
