@@ -41,7 +41,7 @@ When we say that Svelte now supports TypeScript, we mean a few different things:
 * You get autocompletion hints and type-checking as you're writing components, even in expressions inside markup
 * TypeScript files understand the Svelte component API — no more red squiggles when you import a `.svelte` file into a `.ts` module

+### How does it work?
 
 To understand the two main parts of TypeScript support, we'll compare it to the technique TypeScript uses to provide dev tools. There is a compiler `tsc` which you run on the command-line to convert `*.ts` to `*.js`, then there is a `TSServer` which is a node API that responds to requests from text editors. The `TSServer` is what provides all the JavaScript and TypeScript realtime introspection for editors while coding, and it has most of the compiler's code inside it.

 For the editor level, we took inspiration from [Pine's](https://github.com/octref) work in the [Vue](https://vuejs.org) ecosystem via [Vetur](https://github.com/vuejs/vetur). Vetur provides an [LSP](https://github.com/vuejs/vetur/blob/master/server), a VS Code extension and a [CLI](https://github.com/vuejs/vetur/blob/master/vti). Svelte now also has an [LSP](https://github.com/sveltejs/language-tools/blob/master/packages/language-server), a [VS Code extension](https://github.com/sveltejs/language-tools/blob/master/packages/svelte-vscode) and a [CLI](https://github.com/sveltejs/language-tools/blob/master/packages/svelte-check).

 Having red squiggles is great, well, kinda. On the long run though, you want to be able to verify that there are no errors in your code. To verify your project is error free, you can use the CLI tool [`svelte-check`](https://www.npmjs.com/package/svelte-check). It acts like an editor asking for errors against all of your `.svelte` files.
