     You can safely re-run this command after you make changes to your XML schema definition. But if your schema changes require database migrations for existing installations, then you'll need to write a migration manually in addition to re-generating your boilerplate.

     Even though you're not yet creating any upgrades for your extension, you need to do this step now so that CiviCRM will pick up `auto_install.sql` and `auto_uninstall.sql` later on.
     
 1. Re-install your extension.
 
     ```bash
-    $ cv ext:uninstall myextension
-    $ cv ext:enable myextension
+     cv ext:uninstall myextension
+     cv ext:enable myextension
     ```
     
 Now your entity should be ready to use. Try it out with `cv api MyEntity.create` and `cv api MyEntity.get`. Then [add some tests](#generate-test).
