+  Note: in the video I show deleting the roles and permissions, however in the
+  code we no longer do this. As demonstrated in
+  [a previous exercise](https://auth.epicweb.dev/08/02/solution) is we update
+  the migration seed script to create those and we don't use the seed script to
+  create those (so we don't want to delete them either).
