README
Airflow Chef Cookbook
Installs and configures Airflow workflow management platform. More information about Airflow can be found here: https://github.com/airbnb/airflow
Supported Platforms
Ubuntu (Tested on 14.04, 16.04).
CentOS (Tested on 7.2).
Limitations
The Airflow all and oracle packages are not supported, this is due the Oracle package having dependencies which cannot be automatically installed. I will look how to solve this and add support for those packages at later stage.

Please follow instructions in the contributing doc.
