title: Airflow s3 connection using UI
body: <p>I've been trying to use Airflow to schedule a DAG.
  One of the DAG includes a task which loads data from s3 bucket.</p>
  
  <p>For the purpose above I need to setup s3 connection. But UI provided by airflow isn't that intutive (<a href="http://pythonhosted.org/airflow/configuration.html?highlight=connection#connections" rel="noreferrer">http://pythonhosted.org/airflow/configuration.html?highlight=connection#connections</a>). Any one succeeded setting up the s3 connection if so are there any best practices you folks follow?</p>
  
  <p>Thanks.</p>
