+The following environment variables need to be setup for the scripts to deploy database updates:
+
+| Variable             | Description                       | Example                                                                   |

+| DB_HOST_develop      | The database host                 | dbcluster-mr0a782pfjnk.cluster-ctcayu3de2lt.us-east-1.docdb.amazonaws.com |
+| DB_USER_develop      | The database user                 | dbuser                                                                    |

+| SYNAPSE_USERNAME     | The Synapse service user          | syn-service-user                                                          |
