+## Modelo de Datos (Prisma)
+
+### Note
+| Campo | Tipo | Descripción |
+|-------|------|-------------|
+| id | String | CUID único |
+| title | String | Título de la nota |
+| content | String | Contenido en Markdown |
+| type | String | Tipo: command, snippet, decision, recipe, procedure, inventory, note |
+| isFavorite | Boolean | Marcada como favorita |
+| isPinned | Boolean | Fijada arriba |
+| createdAt | DateTime | Fecha creación |
+| updatedAt | DateTime | Última modificación |
+| tags | NoteTag[] | Relación many-to-many |
+
+### Tag
+| Campo | Tipo | Descripción |
+|-------|------|-------------|
+| id | String | CUID único |
+| name | String | Nombre único |
+| notes | NoteTag[] | Relación many-to-many |
+
+### NoteTag (tabla de unión)
+| Campo | Tipo | Descripción |
+|-------|------|-------------|
+| noteId | String | FK a Note |
+| tagId | String | FK a Tag |
+
+---
+
+## Rutas de la Aplicación
+
+| Ruta | Descripción |
+|------|-------------|
+| `/` | Dashboard con notas recientes |
+| `/notes` | Lista de todas las notas con filtros (búsqueda, tipo, tag) |
+| `/notes/[id]` | Detalle de una nota |
+| `/new` | Crear nueva nota |
+| `/edit/[id]` | Editar nota existente |
+| `/settings` | Configuración: exportar/importar notas |
+
+---
+
+## APIs
+
+### GET/POST `/api/export-import`
+- **GET**: Exporta todas las notas como JSON
+- **POST**: Importa notas desde JSON o MD
+  - Soporta `.json` (formato exportado)
+  - Soporta `.md` (usa primer `# Heading` como título)
+
+### GET/POST `/api/notes`
+- **GET**: Lista notas (soporta query params: q, type, tag)
+- **POST**: Crea nueva nota
+
+### GET/PUT/DELETE `/api/notes/[id]`
+- **GET**: Obtiene nota por ID
+- **PUT**: Actualiza nota
+- **DELETE**: Elimina nota
+
+### GET `/api/search`
+- Búsqueda full-text por título y contenido
+
+---
+
+## Funcionalidades Implementadas
+
+1. **CRUD de Notas** - Crear, leer, actualizar, eliminar
+2. **Tipos de Notas** - command, snippet, decision, recipe, procedure, inventory, note
+3. **Tags** - Sistema de tags con many-to-many
+4. **Favoritos y Pins** - Marcar notas como favorites/fijadas
+5. **Búsqueda y Filtros** - Por texto, tipo y tag
+6. **Exportar/Importar** - Formato JSON y MD
+7. **Modal de Confirmación** - Al eliminar nota
+8. **Notas Relacionadas** - Algoritmo de相关性
+9. **Plantillas** - Para diferentes tipos de notas
+10. **Dashboard** - Vista general con notas recientes
+
+---
+
+## Componentes UI Principales
+
+- Button, Card, Badge, Dialog, Input, Select, Tabs, Textarea
+- Avatar, DropdownMenu, Sonner (toasts)
+
+---
+
+## Notas Técnicas
+
+- Uses `app/` router (Next.js 13+ App Router)
+- Server Components para fetching de datos
+- Client Components para interactividad (forms, dialogs)
+- Prisma con SQLite (archivo `dev.db`)
+- Zod para validación de schemas
+- CSS Variables para theming con `next-themes`
