 5. Set your development credentials. These credentials will be used by dbt Cloud to connect to Redshift. Those credentials (as provided in your CloudFormation output) will be:
     - **Username** &mdash; `dbtadmin`
     - **Password** &mdash; This is the autogenerated password that you used earlier in the guide
     - **Schema** &mdash; dbt Cloud automatically generates a schema name for you. By convention, this is `dbt_<first-initial><last-name>`. This is the schema connected directly to your development environment, and it's where your models will be built when running dbt within the Cloud IDE.

 6. Click **Test Connection**. This verifies that dbt Cloud can access your Redshift cluster.
 7. Click **Next** if the test succeeded. If it failed, you might need to check your Redshift settings and credentials.
