+Allowing arbitrary user to run the container
+--------------------------------------------
+
+Airflow image is Open-Shift compatible, which means that you can start it with random user ID and the
+group id ``0`` (``root``). If you want to run the image with user different than Airflow, you MUST set
+GID of the user to ``0``. In case you try to use different group, the entrypoint exits with error.
+
+In order to accommodate a number of external libraries and projects, Airflow will automatically create
+such an arbitrary user in (`/etc/passwd`) and make it's home directory point to ``/home/airflow``.
