-You'll need to create a test app that enables the Flutter driver extension.
-You can put this in your test_driver/ folder, e.g. test_driver/example.dart.
-Replace `<app_package_name>` with the package name of your app. If you're
-developing a plugin, this will be the package name of the example app.
+You'll need to create a driver script that hands off to the
+[`integration_test`](https://pub.dev/packages/integration_test) package so
+`flutter drive`/Espresso can run your Dart integration tests. Put this in your
+`test_driver/` folder, e.g. `test_driver/integration_test.dart`:
