+If you are attaching to a local SQLite file, first make sure that the file is located inside the connector directory. For example, if you had a `data.sqlite` file you could place it at `/app/connector/turso/data.sqlite`. Files in the connector directory get mounted to `/etc/connector/`. 
+
+In this instance, you would set the `TURSO_URL=/etc/connector/data.sqlite` and leave the `TURSO_AUTH_TOKEN` as blank/null. Now your `.env` might look like this:
+
+```
+APP_TURSO_AUTHORIZATION_HEADER="Bearer QTJ7rl19SvKa0rwOZjYILQ=="
+APP_TURSO_HASURA_SERVICE_TOKEN_SECRET="QTJ7rl19SvKa0rwOZjYILQ=="

+
+Your experience mounting files may vary, and while useful to explore a file locally, it's not recommended to attempt to deploy a connector using a locally mounted file.

 ### Step 3: Introspect the connector
 
 Introspecting the connector will generate a `config.json` file and a `turso.hml` file.
