title: Where in the Airflow UI can I add the aws connections?
body: <p>In this <a href="https://github.com/apache/incubator-airflow/blob/master/airflow/contrib/example_dags/example_emr_job_flow_manual_steps.py" rel="nofollow noreferrer">example</a>, I see that the EmrCreateJobFlowOperator receives  the aws/emr connections that were setup in Airflow UI:</p>
  
  <pre><code>cluster_creator = EmrCreateJobFlowOperator(
     task_id='create_job_flow',
     job_flow_overrides=JOB_FLOW_OVERRIDES,
     aws_conn_id='aws_default',
     emr_conn_id='emr_conn_id',
     dag=dag)
  </code></pre>
  
  <p>In Airflow UI, in the tabs of connections, how can I add my AWS credentials so the DAG can pick them up? I don't see any type of connections for AWS. Any idea?</p>
