+Apache Airflow is a platform that allows you to programmatically create,
+schedule, and monitor workflows. In this development sprint, we will guide you
+through the setup of your development environment, help you identify a suitable
+issue to work on and assist you in making your first contribution to Airflow! It
+is strongly recommended to follow through at
+[Airflow Breeze CI environment](https://github.com/apache/airflow/tree/main/dev/breeze/doc)
+since downloading Docker images can be quite time-consuming. If you encounter
+any issues, please feel free to ask questions in
+<https://airflow.apache.org/community/>.
