 It's recommended to install the appropriate adapter to your `devDependencies` once you've settled on a target environment, since this will add the adapter to your lockfile and slightly improve install times on CI.

+title: AWS via SST
+---
+
+To deploy to AWS via SST, use [`svelte-kit-sst`](https://github.com/serverless-stack/sst/tree/master/packages/svelte-kit-sst).
+
+This adapter will be installed by default when you use [`adapter-auto`](adapter-auto), but adding it to your project allows you to specify SST-specific options.
+
+## Usage
+
+Install with `npm i -D svelte-kit-sst`, then add the adapter to your `svelte.config.js`:
+
+```js
+// @errors: 2307 2345
+/// file: svelte.config.js
+import adapter from 'svelte-kit-sst';
+
+export default {
+  kit: {
+    adapter: adapter()
+  }
+};
+```
+
+## Quickstart
+
+1. Create a SvelteKit app
+1. Run `npx create-sst`
+1. It should detect that you are using Svelte and ask you to confirm.
+1. Once you're ready for deployment you can run `npx sst deploy --stage=production`
+
+### SST constructs
+To use any [additional SST constructs](https://docs.sst.dev/), add them to `sst.config.ts`. 
+
+```ts
+/// file: sst.config.ts
+app.stack(function Site(ctx) {
+  const bucket = new Bucket(ctx.stack, "public");
+  const site = new SvelteKitSite(ctx.stack, "site", {
+    bind: [bucket],
+  });
+
+  ctx.stack.addOutputs({
+    url: site.url,
+  });
+});
+```
+
+And then access them in your `+page(.server).ts` file.
+
+```ts
+/// file: +page.server.ts
+import { Bucket } from "sst/node/bucket"
+
+console.log(Bucket.public.bucketName)
+```
+
+Consult the [SST docs on Resource Binding](https://docs.sst.dev/resource-binding) to learn more
+
+If you have any questions, you can [ask in the SST Discord](https://discord.gg/sst).
