+### Update settings.DATABASES
+
+Use the appropriate database connection strings to set your databases. This template uses dj-database-url, so you will just need to set `DATABASE_URL` in your environment.
+
+See [here](https://github.com/jacobian/dj-database-url#url-schema) for additional connection string formats.
+
+If multiple databases are required, you can add to the DATABASES dict:
+
+```python
+'alternate_db': dj_database_url.parse(os.getenv('ALTERNATE_DB_CONN_STRING')),
+```

 ### (Optional) Update settings for Django error emails
