# Enhanced Deployment System

**Complete Automated Deployment for Custom PHP Framework**

The deployment system has been significantly enhanced with production-ready automation, security tools, and user-friendly interfaces that eliminate manual configuration steps.

## 🚀 Quick Start

### Option 1: Interactive Setup Wizard (Recommended)
```bash
cd deployment
./setup-wizard.sh
```

The wizard guides you through:
- Environment selection (development/staging/production)
- Domain and SSL configuration
- Server connection setup
- SSH key generation and testing
- Secure credential generation
- Complete configuration validation

### Option 2: One-Command Production Setup
```bash
cd deployment
./setup-production.sh --server 94.16.110.151 --domain michaelschiemer.de --auto-yes
```

### Option 3: Using the Unified CLI
```bash
cd deployment
./deploy-cli.sh wizard              # Interactive setup
./deploy-cli.sh production          # One-command production
./deploy-cli.sh deploy production   # Deploy to production
```
