+# Nuxt Docs Website
+
+This is a temporary directory until we open source the repository for nuxt.com.
+
+The goal is to simplify the contribution in the meantine to the documentation by having the possibility to preview the changes locally.
+
+## Setup
+
+Install dependencies in the root of the `nuxt` folder:
+
+```bash
+pnpm i
+```
+
+Then stub the dependencies:
+
+```bash
+pnpm build:stub
+```
+
+## Development
+
+In the root of the `nuxt` folder, run:
+
+```bash
+pnpm docs:dev
+```
+
+Then open [http://localhost:3000](http://localhost:3000) with your browser to see the result.
+
+Update the documentation within the `docs` folder.

 ### Crawl-based Pre-rendering
 
-Use the [`nuxi generate` command](/docs/api/commands/generate) to build your application. For every page, Nuxt uses a crawler to generate a corresponding HTML and payload files. The built files will be generated in the `.output/public` directory.
+Use the [`nuxi generate` command](/docs/api/commands/generate) to build and pre-render your application using the [Nitro](/docs/guide/concepts/server-engine) crawler. This command is similar to `nuxt build` with the `nitro.static` option set to `true`, or running `nuxt build --prerender`.
 
 ```bash
 npx nuxi generate
 ```
 
-You can enable crawl-based pre-rendering when using `nuxt build` in the `nuxt.config` file:
+That's it! You can now deploy the `.output/public` directory to any static hosting service or preview it locally with `npx serve .output/public`.
 
-```ts [nuxt.config.ts|js]
+Working of the Nitro crawler:
-defineNuxtConfig({

-  nitro: {
+1. Load the HTML of your application's root route (`/`), any non-dynamic pages in your `~/pages` directory, and any other routes in the `nitro.prerender.routes` array.
-    prerender: {
+2. Save the HTML and `payload.json` to the `~/.output/public/` directory to be served statically.
-      crawlLinks: true
+3. Find all anchor tags (`<a href="...">`) in the HTML to navigate to other routes.
-    }
+4. Repeat steps 1-3 for each anchor tag found until there are no more anchor tags to crawl.
-  }
+
-})
+This is important to understand since pages that are not linked to a discoverable page can't be pre-rendered automatically.

 ### Selective Pre-rendering
 
-You can manually specify routes that [Nitro](/docs/guide/concepts/server-engine) will fetch and pre-render during the build.
+You can manually specify routes that [Nitro](/docs/guide/concepts/server-engine) will fetch and pre-render during the build or ignore routes that you don't want to pre-render like `/dynamic` in the `nuxt.config` file:
 
 ```ts [nuxt.config.ts|js]
 defineNuxtConfig({
   nitro: {
     prerender: {
       routes: ['/user/1', '/user/2']
+      ignore: ['/dynamic']
     }
   }
 })
 ```
 
-When using this option with `nuxi build`, static payloads won't be generated by default at build time. For now, selective payload generation is under an experimental flag.
+You can combine this with the `crawLinks` option to pre-render a set of routes that the crawler can't discover like your `/sitemap.xml` or `/robots.txt`:
 
 ```ts [nuxt.config.ts|js]
 defineNuxtConfig({
-  /* The /dynamic route won't be crawled */
   nitro: {
-    prerender: { crawlLinks: true, ignore: ['/dynamic'] }
+    prerender: {
-  },
+      crawlLinks: true,
-  experimental: {
+      routes: ['/sitemap.xml', '/robots.txt']
-    payloadExtraction: true
+    }
   }
 })
 ```
 
+Setting `nitro.prerender` to `true` is similar to `nitro.prerender.crawlLinks` to `true`.
+
+::alert{type=info}
+Read more about [pre-rendering](https://nitro.unjs.io/config#prerender) in the Nitro documentation.
+::
+
 ### Client-side Only Rendering
 
 If you don't want to pre-render your routes, another way of using static hosting is to set the `ssr` property to `false` in the `nuxt.config` file. The `nuxi generate` command will then output an `.output/public/index.html` entrypoint and JavaScript bundles like a classic client-side Vue.js application.

+Nuxt provide `<NuxtIsland>` to render components only server side.
+
+When rendering an island component, the content of the island component is static, thus no JS is downloaded client-side.
+Changing the island component props triggers a refetch of the island component to re-render it again.

+Slots can be passed to an island component if declared.

+Every slot is interactive since the parent component is the one providing it.
+
+Some slots are reserved to `NuxtIsland` for special cases.

+### Accessing Nuxt Vite Config
+
+If you are building an integration that needs access to the runtime Vite or webpack config that Nuxt uses, it is possible to extract this using Kit utilities.
+
+Some examples of projects doing this already:

+- [@storybook-vue/nuxt](https://github.com/storybook-vue/nuxt/blob/main/src/preset.ts)

+Here is a brief example of how you might access the Vite config from a project; you could implement a similar approach to get the webpack configuration.

+```js
+import { loadNuxt, buildNuxt } from '@nuxt/kit'
