-Aplicación Flutter para registrar órdenes de trabajo de mantenimiento sin depender de conexión a internet.
+Aplicación Flutter para registrar órdenes de trabajo de mantenimiento sin
+depender de conexión a internet.
+
+## Funcionalidades
+
+- Creación y edición de órdenes como borrador.
+- Varias tareas por orden, cada una con su observación.
+- Varias fotografías antes y después por tarea, desde cámara o galería.
+- Persistencia local mediante SQLite y archivos privados de la aplicación.
+- Validación de evidencia antes de finalizar una orden.
+- Informe PDF con el detalle completo y las fotografías.
+- Correo preparado con resumen y PDF adjunto mediante la aplicación de correo
+  configurada en el dispositivo.
+- Consulta, reenvío de correo y eliminación de órdenes guardadas.
+
+## Ejecutar
+
+```bash
+flutter pub get
+flutter run
+```
+
+Para usar cámara, galería y correo se recomienda ejecutar en un teléfono real.
+En Android debe existir una aplicación de correo configurada. En iOS debe haber
+una cuenta disponible para el compositor nativo de Mail.
+
+## Verificar
+
+```bash
+flutter analyze
+flutter test
+```
+
+La información se guarda dentro del espacio privado de la aplicación. Al
+desinstalarla, el sistema operativo puede eliminar la base de datos, las fotos y
+los PDF generados.
