-            ## Usage
-
-            ### Basic Onboarding
-            ```bash
-            onboard --bootcamp-name <bootcamp-name>
-            ```
-
-            ### With Integration Tests
-            If you have a test script to verify API keys:
-            ```bash
-            onboard --bootcamp-name <bootcamp-name> --skip-test
-            python path/to/test_keys.py
-            ```
-
-            Or let onboard run your test script automatically by placing it in the same directory as the CLI.
