You've now finished the Svelte tutorial and are ready to start building apps. You can refer back to individual chapters at any time (click the title above to reveal a dropdown) or continue your learning via the API reference, Examples and Blog. If you're a Twitter user, you can get updates via @sveltejs.
If you're looking for a more expansive framework that includes routing, server-side rendering and everything else, take a look at Sapper.
Most importantly: since you're now a member of the Svelte community, you should join our friendly Discord chatroom. That's where you'll find fellow Svelte users, and it's where we plan the future of the framework.
