+### Athena connection profile
+
+After installing Elementary's dbt package upon running `dbt deps`,
+you can generate Elementary's profile for usage with `edr` by running the following command within your project:
+
+```shell
+dbt run-operation elementary.generate_elementary_cli_profile
+```
+
+The command will print to the terminal a partially filled template of the profile that's needed for `edr` to work.
+
+```yml Athena
+## ATHENA ##
+## By default, edr expects the profile name 'elementary'.      ##
+## Configure the database and schema of elementary models.     ##
+## Check where 'elementary_test_results' is to find it.        ##
