+# Migration Guide to shadcn/ui
+
+This guide helps you migrate from other UI libraries to shadcn/ui.
+
+## Why Migrate to shadcn/ui?
+
+- **Full ownership**: Code lives in your project, not node_modules
+- **Customizable**: Modify any component to fit your needs
+- **No breaking changes**: Update components individually
+- **Smaller bundles**: Only include what you use
+- **Modern stack**: Built with Radix UI and Tailwind CSS
+- **Type-safe**: Full TypeScript support
+
+## Migration Strategies
+
+### Strategy 1: Incremental Migration (Recommended)
+
+Gradually replace components over time:
+
+1. Install shadcn/ui alongside existing library
+2. Replace components page by page or feature by feature
+3. Remove old library once migration is complete
+
+**Pros**: Low risk, can be done alongside feature work
+**Cons**: Temporary bundle size increase
+
+### Strategy 2: Big Bang Migration
+
+Replace all components at once:
+
+1. Set up shadcn/ui
+2. Create component mapping document
+3. Replace all components in one effort
+4. Test thoroughly
+
+**Pros**: Clean cutover, no mixed UI
+**Cons**: High risk, requires dedicated time
+
+## Internal Migrations (shadcn specific)
+
+### RTL Support Migration
+If you need to support RTL languages (like Arabic or Hebrew) in an existing shadcn/ui project:
+
+```bash
+npx shadcn@latest migrate rtl
+```
+
+This CLI command transforms your components to use **logical properties**:
+- `ml-4` -> `ms-4` (margin-start)
+- `pl-4` -> `ps-4` (padding-start)
+- `text-left` -> `text-start`
+
+It ensures your UI adapts correctly to layout direction without manual refactoring.
+
+## From Material-UI (MUI)
+
+### Component Mapping
+
+| MUI Component | shadcn/ui Equivalent | Notes |
+|---------------|----------------------|-------|
+| Button | Button | Similar API |
+| TextField | Input + Label | Separate components |
+| Select | Select | Different structure |
+| Dialog | Dialog | Similar concept |
+| Drawer | Sheet | Side panel |
+| Card | Card | Very similar |
+| Table | Table | Use with TanStack Table |
+| Checkbox | Checkbox | Similar API |
+| Switch | Switch | Similar API |
+| Tabs | Tabs | Similar structure |
+| Tooltip | Tooltip | Simpler API |
+| Menu | Dropdown Menu | Different trigger model |
+| Snackbar | Toast | Different implementation |
+| Autocomplete | Combobox | Use with Command |
+
+### Key Differences
+
+**1. Import Structure**
+```tsx
+// MUI
+import Button from '@mui/material/Button'
+
+// shadcn/ui
+import { Button } from '@/components/ui/button'
+```
+
+**2. Form Components**
+```tsx
+// MUI
+<TextField
+  label="Email"
+  value={email}
+  onChange={(e) => setEmail(e.target.value)}
+  error={!!errors.email}
+  helperText={errors.email}
+/>
+
+// shadcn/ui
+<div className="space-y-2">
+  <Label htmlFor="email">Email</Label>
+  <Input
+    id="email"
+    value={email}
+    onChange={(e) => setEmail(e.target.value)}
+  />
+  {errors.email && (
+    <p className="text-sm text-destructive">{errors.email}</p>
+  )}
+</div>
+
+// Or with Form component
+<FormField
+  control={form.control}
+  name="email"
+  render={({ field }) => (
+    <FormItem>
+      <FormLabel>Email</FormLabel>
+      <FormControl>
+        <Input {...field} />
+      </FormControl>
+      <FormMessage />
+    </FormItem>
+  )}
+/>
+```
+
+**3. Theming**
+```tsx
+// MUI
+import { ThemeProvider, createTheme } from '@mui/material/styles'
+
+const theme = createTheme({
+  palette: {
+    primary: { main: '#1976d2' },
+  },
+})
+
+<ThemeProvider theme={theme}>
+  <App />
+</ThemeProvider>
+
+// shadcn/ui
+// Edit globals.css
+:root {
+  --primary: 215 100% 50%;
+}
+```
+
+**4. Styling Approach**
+```tsx
+// MUI (sx prop)
+<Button sx={{ px: 4, py: 2, borderRadius: 2 }}>
+  Click me
+</Button>
+
+// shadcn/ui (Tailwind classes)
+<Button className="px-4 py-2 rounded-lg">
+  Click me
+</Button>
+```
+
+### Migration Example: Login Form
+
+**Before (MUI)**:
+```tsx
+import { TextField, Button, Box } from '@mui/material'
+
+export function LoginForm() {
+  return (
+    <Box component="form" sx={{ display: 'flex', flexDirection: 'column', gap: 2 }}>
+      <TextField label="Email" type="email" required />
+      <TextField label="Password" type="password" required />
+      <Button variant="contained" type="submit">
+        Sign In
+      </Button>
+    </Box>
+  )
+}
+```
+
+**After (shadcn/ui)**:
+```tsx
+import { Input } from '@/components/ui/input'
+import { Label } from '@/components/ui/label'
+import { Button } from '@/components/ui/button'
+
+export function LoginForm() {
+  return (
+    <form className="flex flex-col gap-4">
+      <div className="space-y-2">
+        <Label htmlFor="email">Email</Label>
+        <Input id="email" type="email" required />
+      </div>
+      <div className="space-y-2">
+        <Label htmlFor="password">Password</Label>
+        <Input id="password" type="password" required />
+      </div>
+      <Button type="submit">Sign In</Button>
+    </form>
+  )
+}
+```

+## From Chakra UI
+
+### Component Mapping
+
+| Chakra UI | shadcn/ui | Notes |
+|-----------|-----------|-------|
+| Button | Button | Similar variants |
+| Input | Input | More basic |
+| Select | Select | Different structure |
+| Modal | Dialog | Similar concept |
+| Drawer | Sheet | Very similar |
+| Box | div | Use Tailwind classes |
+| Flex | div | Use flex utilities |
+| Stack | div | Use space-y-* classes |
+| Text | p/span | Use typography classes |

+</div>
+```
+
+**2. Responsive Styles**
+```tsx
+// Chakra UI
+<Box display={{ base: 'block', md: 'flex' }} />
+
+// shadcn/ui
+<div className="block md:flex" />
+```
+
+**3. Color Mode**
+```tsx
+// Chakra UI
+import { useColorMode } from '@chakra-ui/react'
+
+const { colorMode, toggleColorMode } = useColorMode()
+
+// shadcn/ui (with next-themes)
+import { useTheme } from 'next-themes'
+
+const { theme, setTheme } = useTheme()
+```
+
+## From Ant Design
+
+### Component Mapping

+| Ant Design | shadcn/ui | Notes |
+|------------|-----------|-------|
+| Button | Button | Similar |
+| Input | Input | More basic |
+| Form | Form | Different approach |
+| Table | Table | Use TanStack Table |

+
+### Key Differences
+
+**1. Form Handling**
+```tsx
+// Ant Design
+<Form
+  form={form}
+  onFinish={onSubmit}
+>
+  <Form.Item name="email" rules={[{ required: true }]}>
+    <Input />
+  </Form.Item>
+  <Form.Item>
+    <Button type="primary" htmlType="submit">Submit</Button>
+  </Form.Item>
+</Form>
+
+// shadcn/ui (with react-hook-form)
+<Form {...form}>
+  <form onSubmit={form.handleSubmit(onSubmit)}>
+    <FormField
+      control={form.control}
+      name="email"
+      render={({ field }) => (
+        <FormItem>
+          <FormControl>
+            <Input {...field} />
+          </FormControl>
+          <FormMessage />
+        </FormItem>
+      )}
+    />

+
+## Migration Checklist
+
+### Before Migration
+
+- [ ] Audit current component usage
+- [ ] Set up shadcn/ui in a test branch
+- [ ] Create component mapping document
+- [ ] Plan migration order (start with simple components)
+- [ ] Set up Tailwind CSS properly
+- [ ] Configure path aliases
+
+### During Migration
+
+- [ ] Install shadcn/ui components as needed
+- [ ] Replace components incrementally
+- [ ] Update styling to use Tailwind classes
+- [ ] Test each page/feature after migration
+- [ ] Update tests to match new components
+- [ ] Handle form validation (switch to react-hook-form + zod)
+- [ ] Migrate theme/color variables
+
+### After Migration
+
+- [ ] Remove old UI library dependencies
+- [ ] Clean up unused imports
+- [ ] Optimize bundle size
+- [ ] Update documentation
+- [ ] Review and update design system
+- [ ] Train team on new components
+
+## Common Pitfalls
+
+### 1. Not Setting Up Tailwind Properly
+
+shadcn/ui requires Tailwind. Ensure:
+- `tailwind.config.js` includes correct content paths
+- CSS variables are defined in `globals.css`
+- Tailwind plugins are installed (e.g., `tailwindcss-animate`)
+
+### 2. Forgetting Path Aliases
+
+Components use `@/` imports. Configure:
+- `tsconfig.json` with path aliases
+- Vite/Next.js config for runtime resolution
+
+### 3. Trying to Match Old Library Exactly
+
+Don't force shadcn/ui to work like your old library. Embrace the new patterns:
+- Use composition over configuration
+- Leverage Tailwind utilities
+- Create wrapper components for custom needs
+
+### 4. Not Using Form Libraries
+
+shadcn/ui form components are basic. For complex forms, use:
+- `react-hook-form` for form state
+- `zod` for validation
+- shadcn's `Form` component for integration
+
+### 5. Ignoring Accessibility
+
+While shadcn/ui is accessible by default, custom modifications can break this. Test with:
+- Keyboard navigation
+- Screen readers
+- ARIA attribute validation

+## Next Steps
+
+After migration:
+1. Review the [Customization Guide](./customization-guide.md)
+2. Explore the [Component Catalog](./component-catalog.md)
+3. Check out [Examples](../examples/)
+4. Consider building a component library on top of shadcn/ui
