+# 🧪 Dev Branch Testing Guide
+
+## Übersicht
+
+Dieses Dokument erklärt, wie du dein Portfolio-Projekt auf dem `dev` Branch testen kannst, bevor du es in Production deployst.
+
+## Voraussetzungen
+
+1. ✅ n8n läuft bereits auf `n8n.dk0.dev`
+2. ✅ Gitea Repository ist eingerichtet
+3. ✅ Docker und Docker Compose sind installiert
+
+## Setup für lokales Testen mit n8n
+
+### 1. Environment Variables konfigurieren
+
+Erstelle eine `.env.local` Datei (oder aktualisiere deine bestehende `.env`):
+
+```bash
+# n8n Integration
+N8N_WEBHOOK_URL=https://n8n.dk0.dev
+N8N_API_KEY=dein-n8n-api-key
+N8N_SECRET_TOKEN=dein-n8n-secret-token
+
+# Application
+NODE_ENV=development
+NEXT_PUBLIC_BASE_URL=http://localhost:3000
+
+# Database (wird automatisch von docker-compose.dev.minimal.yml gesetzt)
+# DATABASE_URL=postgresql://portfolio_user:portfolio_dev_pass@localhost:5432/portfolio_dev?schema=public
+
+# Redis (wird automatisch von docker-compose.dev.minimal.yml gesetzt)
+# REDIS_URL=redis://localhost:6379
+
+# Email Configuration
+MY_EMAIL=contact@dk0.dev
+MY_INFO_EMAIL=info@dk0.dev
+MY_PASSWORD=dein-email-passwort
+MY_INFO_PASSWORD=dein-info-email-passwort
+
+# Analytics
+NEXT_PUBLIC_UMAMI_URL=https://analytics.dk0.dev
+NEXT_PUBLIC_UMAMI_WEBSITE_ID=b3665829-927a-4ada-b9bb-fcf24171061e
+
+# Security
+ADMIN_BASIC_AUTH=admin:dein-sicheres-passwort
+LOG_LEVEL=debug
+```
+
+### 2. Lokal testen
+
+```bash
+# 1. Starte Datenbank und Redis
+npm run dev:minimal
+
+# 2. In einem neuen Terminal: Starte die Next.js App
+npm run dev
+
+# 3. Öffne http://localhost:3000
+```
+
+### 3. n8n Webhook testen
+
+Teste die Verbindung zu deinem n8n Server:
+
+```bash
+# Teste den Status Endpoint
+curl https://n8n.dk0.dev/webhook/denshooter-71242/status
+
+# Teste den Chat Endpoint (wenn konfiguriert)
+curl -X POST https://n8n.dk0.dev/webhook/chat \
+  -H "Content-Type: application/json" \
+  -H "Authorization: Bearer DEIN_N8N_SECRET_TOKEN" \
+  -d '{"message": "Hallo", "history": []}'
+```
+
+## Staging Deployment auf dem Server
+
+### 1. Gitea Variables und Secrets konfigurieren
+
+Gehe zu deinem Gitea Repository → Settings → Secrets/Variables und füge hinzu:
+
+**Variables:**
+- `NEXT_PUBLIC_BASE_URL` = `https://staging.dk0.dev` (oder deine Staging URL)
+- `MY_EMAIL` = `contact@dk0.dev`
+- `MY_INFO_EMAIL` = `info@dk0.dev`
+- `NEXT_PUBLIC_UMAMI_URL` = `https://analytics.dk0.dev`
+- `NEXT_PUBLIC_UMAMI_WEBSITE_ID` = `b3665829-927a-4ada-b9bb-fcf24171061e`
+- `N8N_WEBHOOK_URL` = `https://n8n.dk0.dev`
+- `LOG_LEVEL` = `debug`
+
+**Secrets:**
+- `MY_PASSWORD` = Dein Email Passwort
+- `MY_INFO_PASSWORD` = Dein Info Email Passwort
+- `ADMIN_BASIC_AUTH` = `admin:dein-sicheres-passwort`
+- `N8N_API_KEY` = Dein n8n API Key (optional)
+- `N8N_SECRET_TOKEN` = Dein n8n Secret Token (optional)
+
+### 2. Push zum dev Branch
+
+```bash
+# Stelle sicher, dass du auf dem dev Branch bist
+git checkout dev
+
+# Committe deine Änderungen
+git add .
+git commit -m "Test: Dev deployment"
+
+# Push zum dev Branch (triggert automatisch Staging Deployment)
+git push origin dev
+```
+
+### 3. Deployment überwachen
+
+Nach dem Push:
+1. Gehe zu deinem Gitea Repository → Actions
+2. Überwache den Workflow `CI/CD Pipeline (Dev/Staging)`
+3. Der Workflow wird:
+   - Tests ausführen
+   - Docker Image bauen
+   - Staging Container auf Port 3001 deployen
+
+### 4. Staging testen
+
+```bash
+# Auf deinem Server: Prüfe Container Status
+docker ps | grep staging
+
+# Prüfe Health Endpoint
+curl http://localhost:3001/api/health
+
+# Prüfe n8n Status Endpoint
+curl http://localhost:3001/api/n8n/status
+
+# Logs ansehen
+docker logs portfolio-app-staging -f
+```
+
+### 5. Staging URL konfigurieren
+
+Falls du eine Subdomain für Staging hast (z.B. `staging.dk0.dev`):
+- Konfiguriere deinen Reverse Proxy (Nginx/Traefik) um auf Port 3001 zu zeigen
+- Oder verwende direkt `http://dein-server-ip:3001`
+
+## Troubleshooting
+
+### Dev Container wird nicht erstellt
+
+1. **Prüfe Gitea Workflow:**
+   - Gehe zu Repository → Actions
+   - Prüfe ob der Workflow `ci-cd-dev-staging.yml` existiert
+   - Prüfe ob der Workflow auf `dev` Branch Push reagiert
+
+2. **Prüfe Gitea Variables:**
+   - Stelle sicher, dass alle erforderlichen Variables und Secrets gesetzt sind
+   - Prüfe die Workflow Logs für fehlende Variablen
+
+3. **Prüfe Docker:**
+   ```bash
+   # Auf deinem Server
+   docker ps -a
+   docker images | grep portfolio-app
+   ```
+
+### n8n Verbindungsfehler
+
+1. **Prüfe n8n URL:**
+   ```bash
+   # Teste ob n8n erreichbar ist
+   curl https://n8n.dk0.dev/webhook/denshooter-71242/status
+   ```
+
+2. **Prüfe Environment Variables:**
+   ```bash
+   # Im Container
+   docker exec portfolio-app-staging env | grep N8N
+   ```
+
+3. **Prüfe n8n Webhook Konfiguration:**
+   - Stelle sicher, dass der Webhook in n8n aktiviert ist
+   - Prüfe ob der Webhook-Pfad korrekt ist (`/webhook/denshooter-71242/status`)
+
+### Datenbank Fehler
+
+```bash
+# Prüfe ob die Datenbank läuft
+docker ps | grep postgres-staging
+
+# Prüfe Datenbank Logs
+docker logs portfolio-postgres-staging
+
+# Prüfe Verbindung
+docker exec portfolio-postgres-staging pg_isready -U portfolio_user -d portfolio_staging_db
+```

+## Nächste Schritte
+
+1. ✅ Teste lokal mit `npm run dev`
+2. ✅ Konfiguriere Gitea Variables und Secrets
+3. ✅ Push zum `dev` Branch
+4. ✅ Teste Staging auf Port 3001
+5. ✅ Wenn alles funktioniert: Merge zu `production` Branch
