    When you add this step, you'll need to:
 
-   - **Add any [adapters](https://docs.getdbt.com/docs/connect-adapters) used by dbt**. In this example, we're using `dbt-duckdb`.
-   - **Add the location of your dbt project directory** to the `cd` command. In this example, our project is in the `/dbt` directory.
+   - **Add any [adapters](https://docs.getdbt.com/docs/connect-adapters) and libraries used by dbt to your `setup.py` file**. In this example, we're using `dbt-core` and `dbt-duckdb`.
+   - **Add the location of your Dagster project directory** to the `dagster-dbt project prepare-and-package` command. In this example, our project is in the `/my_dbt_and_dagster_project` directory.
