Thank you for considering contributing to Falco, and to those who have already contributed! We appreciate (and actively resolve) PRs of all shapes and sizes.

We kindly ask that before submitting a pull request, you first submit an issue or open a discussion.

If functionality is added to the API, or changed, please kindly update the relevant document. Unit tests must also be added and/or updated before a pull request can be successfully merged.

All pull requests should originate from the develop branch. A merge into this branch means that your changes are scheduled to go into production with the very next release, which could happen any time from the same day up to a couple weeks (depending on priorities and urgency).

Only pull requests which pass all build checks and comply with the general coding guidelines can be approved.
