-svelte@next is not ready for use yet. It definitely can't
-run your apps, and it might not run at all.
-
-We haven't yet started accepting community contributions,
-and we don't need people to start raising issues yet.

-Given these warnings, please feel free to experiment, but
-you're on your own for now. We'll have something to show
-soon.
+Welcome to the SvelteKit setup wizard!
+
+SvelteKit is in public beta now. There are definitely bugs and some feature might not work yet.
+If you encounter an issue, have a look at https://github.com/sveltejs/kit/issues and open a new one, if it is not already tracked.
