+## 🏗️ Construcción de la Imagen
+
+### Construir Imagen Local
+
+Si necesitas modificar el código o construir una imagen personalizada:
+
+```bash
+# Desde la raíz del proyecto
+docker build -t intellidocs-ngx:latest .
+```
+
+### Construir con Soporte GPU (Opcional)
+
+Para usar aceleración GPU con NVIDIA:
+
+1. **Instalar NVIDIA Container Toolkit:**
+   ```bash
+   # Ubuntu/Debian
+   distribution=$(. /etc/os-release;echo $ID$VERSION_ID)
+   curl -s -L https://nvidia.github.io/nvidia-docker/gpgkey | sudo apt-key add -
+   curl -s -L https://nvidia.github.io/nvidia-docker/$distribution/nvidia-docker.list | sudo tee /etc/apt/sources.list.d/nvidia-docker.list
+   sudo apt-get update && sudo apt-get install -y nvidia-container-toolkit
+   sudo systemctl restart docker
+   ```
+
+2. **Modificar docker-compose:**
+   ```yaml
+   services:
+     webserver:
+       # ... otras configuraciones
+       deploy:
+         resources:
+           reservations:
+             devices:
+               - driver: nvidia
+                 count: 1
+                 capabilities: [gpu]
+       environment:
+         - PAPERLESS_USE_GPU=1
+   ```
+
+### Construir para Multi-Arquitectura
+
+```bash
+# Construir para AMD64 y ARM64
+docker buildx build --platform linux/amd64,linux/arm64 -t intellidocs-ngx:latest .
+```
+
+---
+
+## ✅ Verificación de Funciones
+
+### 1. Verificar Contenedores en Ejecución
+
+```bash
+docker compose ps
+```
+
+Deberías ver:
+- `webserver` (IntelliDocs)
+- `broker` (Redis)
+- `db` (PostgreSQL/MariaDB, si aplica)
+
+### 2. Verificar Logs
+
+```bash
+# Ver logs generales
+docker compose logs -f
+
+# Ver logs solo del webserver
+docker compose logs -f webserver
+
+# Buscar errores
+docker compose logs webserver | grep -i error
+```
+
+### 3. Verificar Dependencias ML/OCR
+
+Ejecutar script de verificación dentro del contenedor:
+
+```bash
+# Crear script de test
+docker compose exec webserver bash -c 'cat > /tmp/test_ml.py << EOF
+import sys
+
+print("Testing ML/OCR dependencies...")
+
+try:
+    import torch
+    print(f"✓ torch {torch.__version__}")
+except ImportError as e:
+    print(f"✗ torch: {e}")
+
+try:
+    import transformers
+    print(f"✓ transformers {transformers.__version__}")
+except ImportError as e:
+    print(f"✗ transformers: {e}")
+
+try:
+    import cv2
+    print(f"✓ opencv {cv2.__version__}")
+except ImportError as e:
+    print(f"✗ opencv: {e}")
+
+try:
+    import sentence_transformers
+    print(f"✓ sentence-transformers {sentence_transformers.__version__}")
+except ImportError as e:
+    print(f"✗ sentence-transformers: {e}")
+
+print("\nAll checks completed!")
+EOF
+'
+
+# Ejecutar test
+docker compose exec webserver python /tmp/test_ml.py
+```
+
+### 4. Probar Funciones ML/OCR
+
+Una vez que la aplicación esté corriendo:
+
+1. **Subir un documento de prueba:**
+   - Navega a http://localhost:8000
+   - Sube un documento PDF o imagen
+   - Observa el proceso de OCR en los logs
+
+2. **Verificar clasificación automática:**
+   - Después de procesar, verifica si el documento fue clasificado
+   - Ve a "Documents" → "Tags" para ver tags aplicados
+
+3. **Probar búsqueda semántica:**
+   - Busca por conceptos en lugar de palabras exactas
+   - Ejemplo: busca "factura de electricidad" aunque el documento diga "recibo de luz"
+
+4. **Verificar extracción de tablas:**
+   - Sube un documento con tablas
+   - Verifica que las tablas fueron detectadas y extraídas en los metadatos
+
+---
+
+## 🔧 Troubleshooting
+
+### Problema: Contenedor no inicia / Error de dependencias
+
+**Síntoma**: El contenedor se reinicia constantemente o muestra errores de import.
+
+**Solución**:
+```bash
+# Reconstruir la imagen sin caché
+docker compose build --no-cache
+
+# Reiniciar contenedores
+docker compose down
+docker compose up -d
+
+# Verificar logs
+docker compose logs -f webserver
+```
+
+### Problema: Out of Memory al procesar documentos
+
+**Síntoma**: El contenedor se detiene o está muy lento con documentos grandes.
+
+**Solución**:
+```bash
+# Aumentar memoria asignada a Docker
+# En Docker Desktop: Settings → Resources → Memory → 8GB+
+
+# O limitar procesos simultáneos en docker-compose.env.local:
+PAPERLESS_TASK_WORKERS=1
+PAPERLESS_THREADS_PER_WORKER=1
+```
+
+### Problema: Modelos ML no se descargan
+
+**Síntoma**: Errores sobre modelos no encontrados.
+
+**Solución**:
+```bash
+# Verificar conectividad a Hugging Face
+docker compose exec webserver ping -c 3 huggingface.co
+
+# Descargar modelos manualmente
+docker compose exec webserver python -c "
+from transformers import AutoTokenizer, AutoModel
+model_name = 'distilbert-base-uncased'
+print(f'Downloading {model_name}...')
+AutoTokenizer.from_pretrained(model_name)
+AutoModel.from_pretrained(model_name)
+print('Done!')
+"
+
+# Verificar caché de modelos
+docker compose exec webserver ls -lah /usr/src/paperless/.cache/huggingface/
+```
+
+### Problema: GPU no es detectada
+
+**Síntoma**: PAPERLESS_USE_GPU=1 pero usa CPU.
+
+**Solución**:
+```bash
+# Verificar NVIDIA Docker
+docker run --rm --gpus all nvidia/cuda:11.8.0-base-ubuntu22.04 nvidia-smi
+
+# Verificar dentro del contenedor
+docker compose exec webserver python -c "import torch; print(f'CUDA available: {torch.cuda.is_available()}')"
+```
+
+### Problema: OCR no funciona correctamente
+
+**Síntoma**: Los documentos no son procesados o el texto no es extraído.
+
+**Solución**:
+```bash
+# Verificar Tesseract
+docker compose exec webserver tesseract --version
+
+# Verificar idiomas instalados
+docker compose exec webserver tesseract --list-langs
+
+# Instalar idioma adicional si es necesario
+docker compose exec webserver apt-get update && apt-get install -y tesseract-ocr-spa
+```
+
+### Problema: Permisos de archivos
+
+**Síntoma**: Error al escribir en volúmenes.
+
+**Solución**:
+```bash
+# Ajustar permisos de directorios locales
+sudo chown -R 1000:1000 ./data ./media ./consume ./export ./ml_cache
+
+# O configurar UID/GID en docker-compose.env.local:
+USERMAP_UID=$(id -u)
+USERMAP_GID=$(id -g)
+```
+
+---
+
+## 📊 Monitoreo de Recursos
+
+### Verificar Uso de Recursos
+
+```bash
+# Ver uso de CPU/memoria de contenedores
+docker stats
+
+# Ver solo IntelliDocs
+docker stats $(docker compose ps -q webserver)
+```
+
+### Monitoreo de Modelos ML
+
+```bash
+# Ver tamaño de caché de modelos
+du -sh ./ml_cache/
+
+# Ver modelos descargados
+docker compose exec webserver ls -lh /usr/src/paperless/.cache/huggingface/hub/
+```
+
+---
+
+## 🎓 Mejores Prácticas
+
+### Producción
+
+1. **Usar PostgreSQL en lugar de SQLite**
+   ```bash
+   docker compose -f docker-compose.postgres.yml up -d
+   ```
+
+2. **Configurar backups automáticos**
+   ```bash
+   # Backup de base de datos
+   docker compose exec db pg_dump -U paperless paperless > backup.sql
+   
+   # Backup de media
+   tar -czf media_backup.tar.gz ./media
+   ```
+
+3. **Usar HTTPS con reverse proxy**

+
+### Acceso al contenedor
+
+```bash
+# Shell en webserver
+docker compose -f docker-compose.intellidocs.yml exec webserver bash
+
+# Ejecutar comando de Django
+docker compose -f docker-compose.intellidocs.yml exec webserver python manage.py <command>
+
+# Crear superusuario
+docker compose -f docker-compose.intellidocs.yml exec webserver python manage.py createsuperuser
+```
+
+### Debugging
+
+```bash
+# Ver recursos
+docker stats
+
+# Inspeccionar volúmenes
+docker volume ls
+docker volume inspect docker_ml_cache
+
+# Ver tamaño de caché ML
+docker compose -f docker-compose.intellidocs.yml exec webserver du -sh /usr/src/paperless/.cache/
+```
+
+## 📦 Volúmenes
+
+### Volúmenes Originales
+
+- `data`: Base de datos y configuración
+- `media`: Documentos procesados
+- `export`: Exportaciones
+- `consume`: Documentos a procesar
+
+### Volúmenes Nuevos (IntelliDocs)
+
+- `ml_cache`: **NUEVO** - Caché de modelos ML (~500MB-1GB)
+  - Persiste modelos descargados entre reinicios
+  - Primera descarga puede tomar 5-10 minutos
+  - Ubicación: `/usr/src/paperless/.cache/huggingface/`
+
+## 🔧 Configuración Avanzada
+
+### Activar Soporte GPU
+
+1. Instalar NVIDIA Container Toolkit
+2. En `docker-compose.intellidocs.yml`, descomentar:
+   ```yaml
+   deploy:
+     resources:
+       reservations:
+         devices:
+           - driver: nvidia
+             count: 1
+             capabilities: [gpu]
+   ```
+3. Configurar: `PAPERLESS_USE_GPU=1`
+
+### Ajustar Memoria
+
+Para sistemas con menos RAM:
+
+```yaml
+deploy:
+  resources:
+    limits:
+      memory: 4G  # Reducir de 8G
+    reservations:
+      memory: 2G  # Reducir de 4G
+```
+
+Y configurar workers:
+```bash
+PAPERLESS_TASK_WORKERS=1
+PAPERLESS_THREADS_PER_WORKER=1
+```
+
+### Usar Base de Datos Externa
+
+Modificar `docker-compose.intellidocs.yml` para usar PostgreSQL externo:
+
+```yaml
+environment:
+  PAPERLESS_DBHOST: your-postgres-host
+  PAPERLESS_DBPORT: 5432
+  PAPERLESS_DBNAME: paperless
+  PAPERLESS_DBUSER: paperless
+  PAPERLESS_DBPASS: your-password
+```
+

+
+- **Guía completa**: `/DOCKER_SETUP_INTELLIDOCS.md`
+- **Bitácora del proyecto**: `/BITACORA_MAESTRA.md`
+- **Funciones implementadas**:
+  - Fase 1: `/FASE1_RESUMEN.md` (Performance)
+  - Fase 2: `/FASE2_RESUMEN.md` (Security)
+  - Fase 3: `/FASE3_RESUMEN.md` (AI/ML)
+  - Fase 4: `/FASE4_RESUMEN.md` (Advanced OCR)
+
+## 🐛 Troubleshooting
+
+### Problema: Modelos ML no se descargan
+
+```bash
+# Verificar conectividad
+docker compose -f docker-compose.intellidocs.yml exec webserver ping -c 3 huggingface.co
+
+# Descargar manualmente
+docker compose -f docker-compose.intellidocs.yml exec webserver python -c "
+from transformers import AutoTokenizer, AutoModel
+model = 'distilbert-base-uncased'
+AutoTokenizer.from_pretrained(model)
+AutoModel.from_pretrained(model)
+"
+```
+
+### Problema: Out of Memory
+
+```bash
+# Reducir workers en docker-compose.env.local
+PAPERLESS_TASK_WORKERS=1
+PAPERLESS_THREADS_PER_WORKER=1
+
+# Aumentar memoria de Docker Desktop
+# Settings → Resources → Memory → 8GB+
+```
+
+### Problema: Permisos de archivos
+
+```bash
+# Ajustar permisos
+sudo chown -R 1000:1000 ./data ./media ./consume ./export ./ml_cache
+
+# O configurar UID/GID
+USERMAP_UID=$(id -u)
+USERMAP_GID=$(id -g)
+```
+
+## 🎯 Próximos Pasos
+
+1. ✅ Configurar variables de entorno
+2. ✅ Ejecutar `docker-compose.intellidocs.yml`
+3. ✅ Ejecutar test script
+4. ✅ Crear superusuario
+5. ✅ Subir documentos de prueba
+6. ✅ Verificar funciones ML/OCR
