+# Kitchen Sink: Microfrontends with Astro
+
+```sh
+npm create astro@latest -- --template framework-multiple

+[![Open in StackBlitz](https://developer.stackblitz.com/img/open_in_stackblitz.svg)](https://stackblitz.com/github/withastro/astro/tree/latest/examples/framework-multiple)
+[![Open with CodeSandbox](https://assets.codesandbox.io/github/button-edit-lime.svg)](https://codesandbox.io/p/sandbox/github/withastro/astro/tree/latest/examples/framework-multiple)
+[![Open in GitHub Codespaces](https://github.com/codespaces/badge.svg)](https://codespaces.new/withastro/astro?devcontainer_path=.devcontainer/framework-multiple/devcontainer.json)
+
+This example showcases Astro's built-in support for multiple frameworks ([React](https://react.dev), [Preact](https://preactjs.com), [Svelte](https://svelte.dev), and [Vue (`v3.x`)](https://v3.vuejs.org/)).
+
+No configuration is needed to enable these frameworks—just start writing components in `src/components`.
