---

## Quick Start

```bash
bunx nuxi init my-app && cd my-app
bun add @nuxt/ui tailwindcss
```

```typescript
// nuxt.config.ts
export default defineNuxtConfig({
  modules: ['@nuxt/ui'],
  css: ['~/assets/css/main.css']
})
```

```css
/* assets/css/main.css */
@import "tailwindcss";
@import "@nuxt/ui";
```

```vue
<!-- app.vue -->
<template><UApp><NuxtPage /></UApp></template>
```

**Or use a template**:
```bash
npm create nuxt@latest -- -t ui             # Starter
npm create nuxt@latest -- -t ui/dashboard    # Dashboard
npm create nuxt@latest -- -t ui/chat         # AI Chat
npm create nuxt@latest -- -t ui/landing      # Landing page
npm create nuxt@latest -- -t ui/saas         # SaaS
npm create nuxt@latest -- -t ui/docs         # Documentation
npm create nuxt@latest -- -t ui/portfolio    # Portfolio
npm create nuxt@latest -- -t ui/changelog    # Changelog
npm create nuxt@latest -- -t ui/editor       # Rich text editor
```

**Commands available**: `/nuxt-ui-v4:setup`, `/nuxt-ui:migrate`, `/nuxt-ui:theme`, `/nuxt-ui:component`

## Secure Installation

UI packages modify CSS and component trees — verify before allowing into your project. Follow supply chain security best practices:

- **Block post-install scripts** — `npm config set ignore-scripts true` (or Bun: disabled by default)
- **Cooldown period** — Wait 7 days for new package versions to be vetted by the community
- **Audit before installing** — Run `socket package score npm <pkg>` or use `socket npm install <pkg>` to check packages

Load the `dependency-upgrade` skill for full security configuration including Socket CLI integration, cooldown setup, lockfile validation, and CI enforcement.
