-3. Enable the plugin: `tutor plugins enable example`
-4. Restart the lms service: `tutor dev restart lms`
-5. http://local.openedx.io:8080/ should now successfully fetch the logged in user's name (if available)
+Make sure the plugin is installed, enabled, and then run `tutor dev restart lms` to make sure the new configuration is picked up.
