 ### What is SvelteKit?
 
-SvelteKit is a framework for building extremely high-performance web apps. Building an app with all the modern best practices is fiendishly complicated. Those practices include [build optimizations](https://vitejs.dev/guide/features.html#build-optimizations), so that you load only the minimal required code; [offline support](#service-workers); [prefetching](https://kit.svelte.dev/docs#anchor-options-sveltekit-prefetch) pages before the user initiates navigation; and [configurable rendering](#ssr-and-javascript) that allows you to generate HTML [on the server](#ssr-and-javascript-ssr) or [in the browser](#ssr-and-javascript-router) at runtime or [at build-time](#ssr-and-javascript-prerender). SvelteKit does all the boring stuff for you so that you can get on with the creative part.

 And SvelteKit does this all while providing a lightning-fast development experience where changes to your code show up in your browser automatically. We do this by leveraging [Vite](https://vitejs.dev/) with a [Svelte plugin](https://github.com/sveltejs/vite-plugin-svelte), so that [updates are instant and precise without reloading the page or blowing away application state](https://vitejs.dev/guide/features.html#hot-module-replacement).
