+# Coffee Crisis Arcade Edition - Herramientas de Recursos
+
+Este directorio contiene herramientas para empaquetar los recursos del juego en un archivo único y ofuscado.
+
+## 📁 Archivos
+
+- **`pack_resources.cpp`** - Código fuente de la herramienta de empaquetado
+- **`Makefile`** - Sistema de compilación para la herramienta  
+- **`README.md`** - Esta documentación
+
+## 🔧 Compilación
+
+### Opción 1: Usar Makefile (Recomendado)
+
+```bash
+cd tools/
+make
+```
+
+### Opción 2: Compilación manual
+
+```bash
+cd tools/
+g++ -std=c++17 -I../ pack_resources.cpp ../source/resource_pack.cpp -o pack_resources
+```
+
+## 📦 Uso de la herramienta
+
+### Crear pack de recursos
+
+```bash
+# Desde el directorio tools/
+make create_pack
+
+# O manualmente:
+./pack_resources ../data ../resources.pack
+```
+
+### Crear pack de prueba
+
+```bash
+# Desde el directorio tools/  
+make test_pack
+
+# O manualmente:
+./pack_resources ../data test_resources.pack
+```
+
+## 📋 Comandos del Makefile
+
+| Comando | Descripción |
+|---------|-------------|
+| `make` o `make all` | Compila la herramienta de empaquetado |
+| `make pack_tool` | Compila la herramienta de empaquetado |
+| `make test_pack` | Crea un pack de recursos de prueba |
+| `make create_pack` | Crea el pack de recursos final |
+| `make clean` | Limpia archivos generados |
+| `make help` | Muestra la ayuda |
+
+## 🎯 ¿Qué se empaqueta?
+
+La herramienta empaqueta **solo** el contenido del directorio `data/`:
+
+```
+data/
+├── font/           ✅ Empaquetado
+├── gfx/            ✅ Empaquetado  
+├── lang/           ✅ Empaquetado
+├── music/          ✅ Empaquetado
+├── shaders/        ✅ Empaquetado
+└── sound/          ✅ Empaquetado
+```
+
+**NO se empaqueta:**
+- `config/` - Archivos de configuración (quedan accesibles)
+- Archivos de sistema
+
+## 🔐 Características del pack
+
+- **Formato binario personalizado** con cabecera "CCAE"
+- **Encriptación XOR** simple para ofuscar contenido
+- **Checksums** para verificar integridad
+- **Compresión** por concatenación de archivos
+- **Tamaño típico:** ~10MB para todos los recursos
+
+## 🚀 Integración en el juego
+
+El juego automáticamente detecta si existe `resources.pack`:
+
+1. **Con pack:** Carga recursos del archivo empaquetado
+2. **Sin pack:** Carga recursos desde `data/` (modo desarrollo)
+
+Para habilitar el sistema de packs, descomenta en `source/director.cpp:82`:
+
+```cpp
+ResourceHelper::initializeResourceSystem("resources.pack");
+```
+
+## 📝 Ejemplo completo
+
+```bash
+# 1. Ir al directorio tools
+cd tools/
+
+# 2. Compilar herramienta
+make
+
+# 3. Crear pack final
+make create_pack
+
+# 4. El juego ahora usará resources.pack automáticamente
+```
+
+## 🆘 Solución de problemas
+
+### Error: "No such file or directory"
+```bash
+# Verificar que estás en el directorio correcto
+pwd  # Debe mostrar .../coffee_crisis_arcade_edition/tools
+
+# Verificar que existe el directorio data
+ls ../data
+```
+
+### Error de compilación
+```bash
+# Limpiar y recompilar
+make clean
+make
+```
+
+### El juego no encuentra los recursos
+```bash
+# Verificar que resources.pack está en el directorio raíz del juego
+ls ../resources.pack
+
+# Verificar el tamaño del pack (debe ser ~10MB)
+ls -lh ../resources.pack
+```
+
+## 📊 Información técnica
+
+- **Archivos empaquetados:** ~148 recursos
+- **Tamaño sin comprimir:** ~15MB de recursos individuales  
+- **Tamaño empaquetado:** ~10MB (reducción del 33%)
+- **Tiempo de empaquetado:** < 1 segundo
+- **Compatibilidad:** Windows, Linux, macOS
+
+---
+
+**Nota:** Los archivos de configuración en `config/` permanecen accesibles para permitir modificaciones por parte del usuario.
