+- Using UI components (Button, Card, Table, Form, etc.)
+- Customizing theme (colors, variants, CSS variables)
+- Building forms with validation
+- Using overlays (Modal, Toast, CommandPalette)
+- Working with composables (useToast, useOverlay)
+

+**Load based on context:**
+
+- Installing Nuxt UI? → [references/installation.md](references/installation.md)
+- Customizing theme? → [references/theming.md](references/theming.md)
+- Component index → [references/components.md](references/components.md)
+- Specific component → [components/button.md](components/button.md), [components/modal.md](components/modal.md), etc.
+- Building forms? → [references/forms.md](references/forms.md)
+- Using overlays? → [references/overlays.md](references/overlays.md)
+- Using composables? → [references/composables.md](references/composables.md)
+
+**DO NOT read all files at once.** Load based on context.

+## Key Concepts
+
+| Concept           | Description                                                |
+| ----------------- | ---------------------------------------------------------- |
+| UApp              | Required wrapper component for Toast, Tooltip, overlays    |
+| Tailwind Variants | Type-safe styling with slots, variants, compoundVariants   |
+| Semantic Colors   | primary, secondary, success, error, warning, info, neutral |
+| Reka UI           | Headless component primitives (accessibility built-in)     |
+
+> For headless component primitives (API details, accessibility patterns, asChild): read the **reka-ui** skill
+
+## Quick Reference
+
+```ts
+// nuxt.config.ts
+export default defineNuxtConfig({
+  modules: ['@nuxt/ui'],

+```
+
+```css
+/* assets/css/main.css */
+@import 'tailwindcss';
+@import '@nuxt/ui';
+```
+
+```vue
