 This should work on Linux, MacOS and possibly even Windows.
 
+By default, the devnet is deployed to the `wormhole` namespace rather than `default`. This makes it easy to clean up the
+entire deployment by simply removing the namespace, which isn't possible with `default`. Change your default namespace

 After installing all dependencies, just run `tilt up --update-mode=exec`. 
 Whenever you modify a file, the devnet is automatically rebuilt and a rolling update is done.
