Contributions are welcome and are greatly appreciated! Every little bit helps, and credit will always be given.
This page aims to explain the basic concept of contributions. It contains links to detailed documents for the different aspects of contribution. We encourage both Open Source first timers as well as more experienced contributors to read and learn about this community's contribution guidelines as it support easy and efficient collaboration.
If you are a new contributor, please follow the Contributors Quick Start guide for a step-by-step introduction to setting up the development environment and making your first contribution. We also suggest you to check out Contribution Workflow in order to get an overview of how to contribute to Airflow.
If you are new to the project, you might need some help in understanding how the dynamics
of the community work and hence can consider getting mentorship from other members of the
community - mostly Airflow committers (maintainers). Mentoring new members of the community is part of
maintainers job so do not be afraid to ask them to help you. You can do it
via comments in your PR, asking on a devlist or via Slack. We also have a dedicated #new-contributors Slack channel where you can ask any questions
about making your first Pull Request (PR) contribution to the Airflow codebase - it's a safe space
where it is expected that people asking questions do not know a lot Airflow (yet!).
If you need help with Airflow see the Slack channel #user-troubleshooting.
