+
+## Generating Password Hashes
+
+To create password hashes for your users, use one of these methods:
+
+### Using Docker:
+
+```bash
+docker exec -it axia4-app php -r "echo password_hash('your_password', PASSWORD_DEFAULT);"
+```
+
+### Using PHP CLI directly:
+
+```bash
+php -r "echo password_hash('your_password', PASSWORD_DEFAULT);"
+```
+
+### Using a PHP script:
+
+```php
+<?php
+echo password_hash('your_password', PASSWORD_DEFAULT);
+?>
+```
+
+## Security Notes
+
+- **NEVER** commit the actual DATA directory with real user credentials to version control
+- The DATA directory should only exist on your production/development servers
+- Use strong, unique passwords for all accounts
+- Regularly backup the DATA directory
+- Set appropriate file permissions (755 for directories, 644 for files)

+# Axia4 Docker Setup
+
+This document explains how to run the Axia4 PHP application using Docker.
+
+## Prerequisites
+
+- Docker Engine 20.10+
+- Docker Compose V2
+
+## Quick Start
+
+1. **Prepare the data directory**
+   ```bash
+   mkdir -p DATA/entreaulas/Usuarios
+   mkdir -p DATA/entreaulas/Centros
+   ```
+
+2. **Build and start the application**
+   ```bash
+   docker-compose up -d
+   ```
+
+3. **Access the application**
+   
+   Open your browser and navigate to: `http://localhost:8080`
+
+## Configuration
+
+### Data Directory Structure
+
+The application stores all data in the `/DATA` directory which is mounted from `./DATA` on the host:
+
+```
+DATA/
+├── Usuarios.json                          # Main user accounts
+└── entreaulas/
+    ├── Usuarios/                          # EntreAulas user files
+    │   └── {username}.json
+    └── Centros/                           # Centro data
+        └── {centro_id}/
+            └── Aularios/                  # Aulario configurations
+                └── {aulario_id}.json
+```
+
+### Creating Initial Users
+
+**Main Users** (`DATA/Usuarios.json`):
+```json
+{
+  "username": {
+    "password_hash": "hashed_password_here"
+  }
+}
+```
+
+**EntreAulas Users** (`DATA/entreaulas/Usuarios/{username}.json`):
+```json
+{
+  "password_hash": "hashed_password_here",
+  "display_name": "Full Name",
+  "centro": "centro_id",
+  "aulas": ["aulario_id_1", "aulario_id_2"]
+}
+```
+
+To generate a password hash, you can use PHP:
+```bash
+docker exec -it axia4-app php -r "echo password_hash('your_password', PASSWORD_DEFAULT);"
+```
+
+### Port Configuration
+
+By default, the application runs on port 8080. To change this, edit `docker-compose.yml`:
+
+```yaml
+ports:
+  - "YOUR_PORT:80"
+```
+
+## Docker Commands
+
+### Start the application
+```bash
+docker-compose up -d
+```
+
+### Stop the application
+```bash
+docker-compose down
+```
+
+### View logs
+```bash
+docker-compose logs -f
+```
+
+### Rebuild after changes
+```bash
+docker-compose up -d --build
+```
+
+### Access the container shell
+```bash
+docker exec -it axia4-app bash
+```
+
+## Development Mode
+
+To enable live code updates without rebuilding, uncomment the volume mount in `docker-compose.yml`:
+
+```yaml
+volumes:
+  - ./DATA:/DATA
+  - ./public_html:/var/www/html  # Uncomment this line
+```
+
+## Troubleshooting
+
+### Permission Issues
+
+If you encounter permission errors with the DATA directory:
+
+```bash
+sudo chown -R 33:33 DATA
+sudo chmod -R 755 DATA
+```
+
+(User ID 33 is typically the www-data user in the container)
+
+### Check Application Logs
+
+```bash
+docker-compose logs axia4-web
+```
+
+### Inspect Container
+
+```bash
+docker exec -it axia4-app bash
+# Then inside the container:
+ls -la /DATA
+cat /var/log/apache2/error.log
+```
+
+## Security Notes
+
+- Change default passwords immediately in production
+- Ensure the DATA directory has appropriate permissions
+- Consider using environment variables for sensitive configuration
+- Use HTTPS in production (add a reverse proxy like Nginx or Traefik)
+
+## Backup
+
+To backup your data:
+
+```bash
+tar -czf axia4-data-backup-$(date +%Y%m%d).tar.gz DATA/
+```
+
+## Restore
+
+To restore from backup:
+
+```bash
+tar -xzf axia4-data-backup-YYYYMMDD.tar.gz
+```

+# Dockerization Implementation Summary
+
+## Overview
+Successfully dockerized the Axia4 PHP application and migrated all data references to use the `/DATA/` directory for better portability and consistency.
+
+## Changes Made
+
+### 1. Docker Configuration Files
+
+#### Dockerfile
+- Base image: `php:8.2-apache`
+- Installed PHP extensions: GD (with freetype and jpeg support)
+- Enabled Apache modules: `rewrite`
+- Configured PHP session settings for longer lifetime (7 days)
+- Created `/DATA` directory with proper permissions
+- Set up Apache document root at `/var/www/html`
+
+#### docker-compose.yml
+- Service: `axia4-web` running on port 8080
+- Volume mount: `./DATA:/DATA` for persistent storage
+- Network: `axia4-network` for container isolation
+- Environment variables support via `.env` file
+- Restart policy: `unless-stopped`
+
+#### Supporting Files
+- `.dockerignore`: Excludes unnecessary files from build context
+- `.env.example`: Template for environment configuration
+- Updated `.gitignore`: Excludes Docker runtime files and DATA directory
+
+### 2. Data Path Migration
+
+All data file paths were updated from hardcoded system-specific paths to use the `/DATA/` directory:
+
+#### Main Application
+- `/mnt/dietpi_userdata/www_userdata/Usuarios.json` → `/DATA/Usuarios.json`
+
+#### EntreAulas Module
+- `/srv/storage/entreaulas/Usuarios/*.json` → `/DATA/entreaulas/Usuarios/*.json`
+- `/srv/storage/entreaulas/Centros/*/Aularios/*.json` → `/DATA/entreaulas/Centros/*/Aularios/*.json`
+
+#### Files Modified
+- `public_html/_login.php`
+- `public_html/entreaulas/_login.php`
+- `public_html/entreaulas/_incl/auth_redir.php`
+- `public_html/entreaulas/index.php`
+- `public_html/entreaulas/aulario.php`
+- `public_html/entreaulas/admin/aularios.php`
+
+### 3. Path Portability Fixes
+
+Fixed hardcoded `/var/www/` paths to use relative paths:
+
+#### Files Modified
+- `public_html/_incl/pre-body.php`:
+  - Changed `/var/www/_autoreload.php` → `__DIR__ . "/../_autoreload.php"`
+  - Changed `/var/www$APP_ROOT/__menu.php` → `__DIR__ . "/.." . $APP_ROOT . "/__menu.php"`
+- `public_html/entreaulas/_incl/pre-body.php`:
+  - Changed `/var/www/_incl/pre-body.php` → `__DIR__ . "/../../_incl/pre-body.php"`
+
+### 4. Documentation
+
+Created comprehensive documentation:
+
+#### DOCKER.md
+- Quick start guide
+- Data directory structure explanation
+- Configuration instructions
+- Docker commands reference
+- Development mode setup
+- Troubleshooting guide
+- Security notes
+- Backup and restore procedures
+
+#### DATA_STRUCTURE.md
+- Complete data directory structure
+- JSON file format examples
+- Password hash generation instructions
+- Security best practices
+
+#### README.md
+- Updated with Docker quick start
+- Links to detailed documentation
+- Feature overview
+- Requirements section
+- Development setup guide
+
+## Testing
+
+All changes were tested and verified:
+
+✅ Docker image builds successfully  
+✅ Container starts without errors  
+✅ Main page loads correctly (HTTP 200)  
+✅ EntreAulas module loads correctly (HTTP 200)  
+✅ DATA directory is properly mounted  
+✅ Application can read from DATA/Usuarios.json  
+✅ No hardcoded paths remain in the codebase  
+✅ Code review completed with all issues addressed  
+
+## Benefits
+
+1. **Portability**: Application can run on any system with Docker
+2. **Consistency**: Same environment across development, staging, and production
+3. **Easy Setup**: One-command deployment with `docker compose up`
+4. **Data Isolation**: All data in a single `/DATA` directory
+5. **Clean Architecture**: Separation of code and data
+6. **Documentation**: Comprehensive guides for setup and usage
+
+## Usage
+
+### Quick Start
+```bash
+# Clone and navigate to repository
+git clone https://github.com/Axia4/Axia4.git
+cd Axia4
+
+# Create data directories
+mkdir -p DATA/entreaulas/Usuarios
+mkdir -p DATA/entreaulas/Centros
+
+# Start the application
+docker compose up -d
+
+# Access at http://localhost:8080
+```
+
+### Customization
+- Port: Change in `.env` or `docker-compose.yml`
+- Data location: Update `DATA_DIR` in `.env`
+- Development: Uncomment code volume mount in `docker-compose.yml`
+
+## Security Notes
+
+- DATA directory excluded from version control
+- Password hashing using PHP's `password_hash()`
+- Session security configured (cookie lifetime, secure flags)
+- Proper file permissions set in container
+- No sensitive data in Docker image
+
+## Future Improvements
+
+Potential enhancements:
+- Add HTTPS support with reverse proxy (Nginx/Traefik)
+- Implement environment-based configuration
+- Add health checks to docker-compose
+- Create Docker multi-stage build for smaller image
+- Add database container if needed in future
+
+## Conclusion
+
+The Axia4 application is now fully containerized with Docker, making it easy to deploy, maintain, and scale. All data references use a consistent `/DATA/` directory structure, and comprehensive documentation is provided for users and developers.
