 In Storybook 7, we would automatically add frameworks-specific Vite plugins, e.g. `@vitejs/plugin-react` if not installed.
 In Storybook 8 those plugins have to be added explicitly in the user's `vite.config.ts`:
 
+#### For React:
+
 ```ts
 import { defineConfig } from "vite";
 import react from "@vitejs/plugin-react";
 
-// https://vitejs.dev/config/
 export default defineConfig({
   plugins: [react()],
 });
 ```
 
+#### For Vue:
+
+```ts
+import { defineConfig } from "vite";
+import vue from "@vitejs/plugin-vue";
+
+export default defineConfig({
+  plugins: [vue()],
+});
+```
+
+#### For Svelte (without Sveltekit):
+
+```ts
+import { defineConfig } from "vite";
+import svelte from "@sveltejs/vite-plugin-svelte";
+
+export default defineConfig({
+  plugins: [svelte()],
+});
+```
+
+#### For Preact:
+
+```ts
+import { defineConfig } from "vite";
+import preact from "@preact/preset-vite";
+
+export default defineConfig({
+  plugins: [preact()],
+});
+```
+
+#### For Solid:
+
+```ts
+import { defineConfig } from "vite";
+import solid from "vite-plugin-solid";
+
+export default defineConfig({
+  plugins: [solid()],
+});
+```
+
+#### For Qwik:
+
+```ts
+import { defineConfig } from "vite";
+import qwik from "vite-plugin-qwik";
+
+export default defineConfig({
+  plugins: [qwik()],
+});
+```
+
 ### TurboSnap Vite plugin is no longer needed
 
 At least in build mode, `builder-vite` now supports the `--webpack-stats-json` flag and will output `preview-stats.json`.
