+'@astrojs/prefetch': patch
+---
+
+Adds a new `@astrojs/prefetch` integration with the goal of adding near-instant page navigation for Astro projects. HTML and CSS for visible links marked with `rel="prefetch"` will be preloaded in the browser when the browser is idle.
+
+__astro.config.mjs__
+```js
+import prefetch from '@astrojs/prefetch';
+export default {
+  // ...
+  integrations: [prefetch()],
+}
+```
+
+```html
+<!-- Prefetch HTML and stylesheets for the /products page -->
+<a href="/products" rel="prefetch">All Products</a>
+```
