+## Dependencias Principales
+- Django==5.0.6
+- djangorestframework
+- django-cors-headers
+- djangorestframework-simplejwt
+- sabatron-tryton-rpc-client==7.4.0 (integración con Tryton ERP)
+
+## Modelos Principales (don_confiao/models.py)
+- **Customer**: Clientes (name, address, email, phone, external_id)
+- **Product**: Productos (name, price, measuring_unit, categories)
+- **ProductCategory**: Categorías de productos
+- **Sale**: Ventas (customer, date, phone, description, payment_method, reconciliation)
+- **SaleLine**: Líneas de venta (sale, product, quantity, unit_price, description)
+- **Payment**: Pagos (date_time, type_payment, amount, reconciliation_jar)
+- **PaymentSale**: Relación muchos a muchos entre Payment y Sale
+- **ReconciliationJar**: Arqueo de caja (is_valid, date_time, reconcilier, cash_taken, cash_discrepancy)
+- **AdminCode**: Códigos de administrador
+
+## Autenticación
+- JWT con djangorestframework-simplejwt
+- ACCESS_TOKEN_LIFETIME: 30 minutos
+- REFRESH_TOKEN_LIFETIME: 1 día
+
+## API Endpoints
+- REST API en don_confiao/api_views.py y users/
+- URLs en don_confiao/urls.py y users/urls.py
+
+## Ejecución con Docker Compose
+
+El proyecto se ejecuta con docker-compose. Todos los comandos `manage.py` deben ejecutarse dentro del contenedor:
+
+```bash
+# Ejecutar tests
+docker-compose run --rm django python manage.py test
+
+# Migraciones
+docker-compose run --rm django python manage.py makemigrations
+docker-compose run --rm django python manage.py migrate
+
+# Servidor desarrollo
+docker-compose up
+
+# Shell Django
+docker-compose run --rm django python manage.py shell
+
+# Crear superuser
+docker-compose run --rm django python manage.py createsuperuser
+```
+
+Nota: El volumen monta `tienda_ilusion/` en `/app/`, por lo que el path correcto es `python manage.py` (no `python tienda_ilusion/manage.py`).
+
+## Tests
+- Framework: Django unittest
+- Directorio: don_confiao/tests/
+- Ejecutar: `docker-compose run --rm django python manage.py test`
+
+## Comandos Útiles (dentro del contenedor)
+- Migraciones: `docker-compose run --rm django python manage.py makemigrations && docker-compose run --rm django python manage.py migrate`
+- Servidor desarrollo: `docker-compose up`
+- Shell Django: `docker-compose run --rm django python manage.py shell`
+- Superuser: `docker-compose run --rm django python manage.py createsuperuser`
+
+## Integraciones
+- **Tryton ERP**: Integración mediante sabatron-tryton-rpc-client para sincronización de clientes, productos y ventas
