-This package is an example of a Backstage application.
+This package is an example of a Backstage application using the [new frontend](../../docs/frontend-system/index.md).
+
+To play with it, open a terminal and run the command: `yarn start`
+
+**NOTE:** Don't forget to open a second terminal and to launch the backend or [backend-next](../../docs/backend-system/index.md) there, using `yarn start`! The frontend requires a backend to connect to.
