+# 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
+```
