+# Shared Components - AvanzaCast
+
+Componentes reutilizables compartidos entre todos los paquetes del monorepo AvanzaCast.
+
+## Estructura

+│   ├── ModalLink.tsx                  # Enlaces azules estilo StreamYard
+│   ├── ModalCopyInput.tsx             # Input + botón copiar

+```
+
+## Uso en Paquetes
+
+### Configuración TypeScript
+
+Cada paquete debe configurar su `tsconfig.json`:
+
+```json
+{
+  "extends": "../../tsconfig.json",
+  "compilerOptions": {
+    "baseUrl": "../..",
+    "paths": {
+      "@/*": ["packages/[paquete]/src/*"],
+      "@shared/*": ["shared/*"]
+    }
+  },
+  "include": ["src", "../../shared"]
+}
+```
+
+### Configuración Vite
+
+Agregar alias en `vite.config.ts`:
+
+```typescript
+import { defineConfig } from 'vite'
+import react from '@vitejs/plugin-react'
+import path from 'path'
+
+export default defineConfig({
+  plugins: [react()],
+  resolve: {
+    alias: {
+      '@': path.resolve(__dirname, './src'),
+      '@shared': path.resolve(__dirname, '../../shared')
+    }
+  }
+})
+```
+
+### Importación
+
+```typescript
+// Importar componentes individuales
+import { Modal, ModalLink, ModalCopyInput } from '@shared/components'
+
+// O usando path completo
+import { Modal } from '@shared/components/Modal'
+import { ModalLink } from '@shared/components/modal-parts/ModalLink'
+```
+
+## Componentes Disponibles
+
+### Modal System
+
+- **Modal**: Componente base usando `<dialog>` nativo
+- **ModalLink**: Enlaces azules subrayados
+- **ModalCopyInput**: Input con botón de copiar
+- **ModalShareButtons**: Botones de compartir en redes sociales
+- **ModalToggle**: Toggle switch con icono de ayuda
+
+Ver documentación completa en `modal-parts/README.md`
+
+### UI Components
+
+- **LanguageSelector**: Selector de idioma multilenguaje
+- **AuthButton**: Botón de autenticación/login
+
+## Diseño y Estilo
+
+Todos los componentes siguen el sistema de diseño de **StreamYard/Google Material**:
+
+- **Colores**: `#1a73e8` (primary blue), `#202124` (text), `#5f6368` (secondary)
+- **Espaciado**: Múltiplos de 4px (8px, 12px, 16px, 24px)
+- **Bordes**: Border radius 4px
+- **Tipografía**: 14px body, 16px títulos
+- **Dark Mode**: Soporte completo con atributo `[data-theme="dark"]`
+
+## Ventajas
+
+✅ **Reutilización**: Un solo componente usado en todos los paquetes  
+✅ **Mantenibilidad**: Cambios centralizados  
+✅ **Consistencia**: Diseño uniforme en toda la aplicación  
+✅ **Performance**: Code splitting automático con Vite  
+✅ **TypeScript**: Tipado completo y autocomplete  
+✅ **Testing**: Un solo lugar para testear componentes
+
+## Agregar Nuevos Componentes
+
+1. Crear componente en `shared/components/`
+2. Agregar estilos en `.module.css`
+3. Exportar en `index.ts`
+4. Documentar en este README
+5. Importar usando `@shared/components`
+
+## Ejemplos
+
+Ver `packages/broadcast-panel/src/components/` para ejemplos de uso:
+
+- `InviteGuestsModal.tsx` - Uso completo del sistema modular
+- `NewTransmissionModal.tsx` - Modal con formulario
+- `ExampleModal.tsx` - Demostración de todos los componentes
