+## 🚀 Quick Start
+
+### Using Hooks
+
+```tsx
+import { useDebounce, usePagination, useSelection } from '@/hooks'
+
+function MyComponent() {
+  const [search, setSearch] = useState('')
+  const debouncedSearch = useDebounce(search, 300)
+  
+  const { paginatedItems, nextPage, previousPage } = usePagination(items, 10)
+  
+  const { selectedIds, toggleSelection, selectAll } = useSelection(items)
+  
+  return (
+    // Your component JSX
+  )
+}
+```
+
+### Using UI Components
+
+```tsx
+import { EmptyState, StatusBadge, SearchInput } from '@/components/ui'
+import { FileX } from '@phosphor-icons/react'
+
+function MyView() {
+  return (
+    <div>
+      <SearchInput
+        value={search}
+        onChange={(e) => setSearch(e.target.value)}
+        onClear={() => setSearch('')}
+      />
+      
+      <StatusBadge status="success" label="Active" />
+      
+      <EmptyState
+        icon={<FileX size={48} />}
+        title="No results found"
+        description="Try adjusting your search"
+      />
+    </div>
+  )
+}
+```
+
+## 📖 Documentation
+
+Detailed documentation available:
+- `/src/hooks/README.md` - Complete hook documentation with examples
+- `/src/components/ui/README.md` - UI component reference
+
+## 🎯 Common Use Cases
+
+### Data Tables
+Combine `useFilter`, `useSort`, `usePagination`, and `useSelection` for full-featured data tables.
+
+### Multi-Step Forms
+Use `useWizard` with `Stepper` component for intuitive form flows.
+
+### Search Functionality
+Pair `useDebounce` with `SearchInput` for optimized search experiences.
+
+### Loading States
+Use `LoadingOverlay` or `LoadingSpinner` with `useAsync` for async operations.
+
+### Status Display
+Use `StatusBadge` consistently across the platform for status indicators.
+
+### Empty States
+Always show meaningful `EmptyState` components when data is not available.
+
+## 🔧 Development Guidelines
+
+1. **Consistency** - Use library components before creating custom ones
+2. **Composition** - Combine hooks and components for complex functionality
+3. **Performance** - Leverage `useDebounce` and `useThrottle` for expensive operations
+4. **Accessibility** - All components include ARIA attributes and keyboard support
+5. **Styling** - Extend components with Tailwind classes via `className` prop
+
+## 📦 Import Paths
+
+```tsx
+// Hooks
+import { hookName } from '@/hooks'
+
+// UI Components
+import { ComponentName } from '@/components/ui/component-name'
+
+// Or use existing barrel exports
+import { Button, Card, Dialog } from '@/components/ui'
+```
+
+## 🎨 Theming
+
+All components respect the application theme defined in `/src/index.css`:
+- Primary, secondary, accent colors
+- Success, warning, error, info colors
+- Border radius and spacing
+- Typography scale
+
+## 🔍 Finding Components
+
+**Need a component?** Check these locations in order:
+1. New extended components: `/src/components/ui/README.md`
+2. shadcn components: `/src/components/ui/` directory
+3. Custom hooks: `/src/hooks/README.md`
+
+## 🤝 Contributing
+
+When adding new hooks or components:
+1. Follow existing patterns and conventions
+2. Add TypeScript types for all props
+3. Include forwardRef for DOM components
+4. Support className for styling
+5. Document usage in respective README
+6. Export from index files

+
+### Data Table with Pagination
+```tsx
+import { usePagination, SearchInput, EmptyState } from '@/hooks'
+
+const { paginatedItems, currentPage, totalPages, nextPage, previousPage } = 
+  usePagination(items, 10)
+
+return (
+  <div>
+    <SearchInput value={search} onChange={e => setSearch(e.target.value)} />
+    {paginatedItems.length === 0 ? (
+      <EmptyState title="No results" />
+    ) : (
+      <Table items={paginatedItems} />
+    )}
+  </div>
+)
+```

+  { id: '3', title: 'Complete' }
+]
+
+const { currentStep, goToNextStep, isLastStep } = useWizard(steps)
+
+return (
+  <div>
+    <Stepper steps={steps} currentStep={currentStepIndex} />
+    {/* Step content */}
+    <Button onClick={goToNextStep} disabled={isLastStep}>
+      {isLastStep ? 'Complete' : 'Next'}
+    </Button>
+  </div>
+)
+```
+
+### Status Display
+```tsx
+import { StatusBadge } from '@/components/ui/status-badge'
+
+<StatusBadge status="success" label="Approved" />
+<StatusBadge status="pending" label="Under Review" />
+<StatusBadge status="error" label="Rejected" />
+```
+
+### Form Validation
+```tsx
+import { useFormValidation } from '@/hooks'
+
+const { values, errors, handleChange, validateAll } = useFormValidation(
+  { email: '', password: '' },
+  {
+    email: val => !val.includes('@') ? 'Invalid email' : undefined,

+All components support standard HTML attributes and can be styled using Tailwind classes via the `className` prop.
+
+## Accessibility
+
+All components are built with accessibility in mind:
+- Semantic HTML elements
+- ARIA labels where appropriate
+- Keyboard navigation support
+- Focus management
