 npm install @nativescript/vite

+## Quick start (`init`)
+
+To bootstrap an existing NativeScript app for Vite, run from your app root:
+
+```bash
+npx nativescript-vite init
+```
+
+This will:
+
+- Generate a `vite.config.ts` using the detected project flavor (Angular, Vue, React, Solid, TypeScript, or JavaScript) and the corresponding helper from `@nativescript/vite`.
+- Add (or update) the following npm scripts in your app `package.json`:
+	- `dev:ios`
+	- `dev:android`
+	- `dev:server:ios`
+	- `dev:server:android`
+	- `ios`
+	- `android`
+- Add the devDependencies `concurrently` and `wait-on`.
+- Add the dependency `@valor/nativescript-websockets`.
+- Append `.ns-vite-build` to `.gitignore` if it is not already present.
+
+After running `init`, you now have two ways to work with Vite:
+
+1. HMR workflow
+
+```bash
+npm run dev:ios
+```
+
+2. Standard dev workflow (non-HMR)
+
+```bash
+ns debug ios --no-hmr
+ns debug android --no-hmr
+```
+
 ## Configure
 
 The plugin comes with several framework integrations.
