+#### Opción B: Ejecución en Windows (Híbrida)
+
+1.  Asegúrate de tener **Docker Desktop** corriendo.
+2.  Abre la carpeta `alpr-service`.
+3.  Haz doble clic en el archivo `run_windows.bat`.
+    *   Este script instalará las dependencias automáticamente.
+    *   Configurará las variables de entorno.
+    *   Iniciará el reconocimiento de patentes.

+#### Opción C: Ejecución Full Docker (Linux / Raspberry Pi)
 
 En sistemas Linux nativos donde se pueden mapear dispositivos (ej. `/dev/video0`), simplemente descomenta la sección `devices` en `docker-compose.yml` y todo correrá dentro de Docker.
