+### 🎯 Single Container Setup (Önerilen)
 
-### Başlatma
+**Tek container, tek port (3000)** - En basit ve önerilen yöntem!
+
+Single container setup'ta:
+- ✅ **Tek Port**: Sadece 3000 portu kullanılır
+- ✅ **Backend + Frontend**: Backend hem API'yi hem frontend'i serve eder
+- ✅ **CORS Yok**: Aynı origin'den geldiği için CORS sorunu yok
+- ✅ **Daha Az Kaynak**: Tek container, daha az memory/CPU
+- ✅ **Basit Yönetim**: Tek container yönetimi
+
+#### Başlatma
+
+```bash
+# Single container ile başlat
+docker compose -f docker-compose.single.yml up -d --build
+
+# Durum kontrolü
+docker compose -f docker-compose.single.yml ps
+
+# Logları görüntüle
+docker compose -f docker-compose.single.yml logs -f oltalama
+```
+
+#### Port Yapısı
+
+```
+Tek Port: 3000
+├── /api/* → Backend API
+├── /t/* → Tracking routes
+├── /health → Health check
+└── /* → Frontend SPA (React Router)
+```
+
+#### Nginx Proxy Manager Konfigürasyonu
+
+Single container için:
+- **Forward Hostname/IP**: `localhost`
+- **Forward Port**: `3000`
+- **SSL**: ✓ (Let's Encrypt)
+- **Websockets**: ✓ (opsiyonel)
+
+Tüm trafik (API + Frontend) → `localhost:3000`
+
+#### Erişim
+
+- **Frontend + API**: http://localhost:3000
+- **Health Check**: http://localhost:3000/health
+- **API Endpoint**: http://localhost:3000/api
