+
+## 🚀 Deployment Options
+
+### Option 1: Manual Deployment (Quick Start)
+
+```bash
+# 1. Provision Hetzner VM (Ubuntu 22.04)
+# 2. Install Docker + Docker Compose
+ssh root@YOUR_HETZNER_IP "apt update && apt install -y docker.io docker-compose"
+
+# 3. Copy files to server
+scp -r . root@YOUR_HETZNER_IP:/opt/mintel
+
+# 4. Set environment variables
+ssh root@YOUR_HETZNER_IP "cat > /opt/mintel/.env << EOF
+DOMAIN=mintel.me
+ADMIN_EMAIL=admin@mintel.me
+REDIS_URL=redis://redis:6379
+EOF"
+
+# 5. Deploy
+ssh root@YOUR_HETZNER_IP "cd /opt/mintel && ./deploy.sh"
+```
+
+### Option 2: CI/CD with Woodpecker + Gitea (Recommended)
+
+Your existing Woodpecker + Gitea setup will handle automatic deployments:
+
+1. **Configure Woodpecker secrets** in your Gitea repo:
+   - `SSH_PRIVATE_KEY` - Private key for Hetzner access
+   - `DEPLOY_HOST` - Hetzner server IP
+   - `DEPLOY_USER` - Usually `root`
+   - `DOMAIN` - Your domain
+   - `ADMIN_EMAIL` - Contact email
+
+2. **Push to main branch** triggers automatic deployment
+
+## 🔧 Environment Variables
+
+See [ENV_SETUP.md](./ENV_SETUP.md) for detailed configuration guide.
+
+**Quick setup:**
+```bash
+cp .env.example .env
+# Edit .env with your values
+```
+
+**Required variables:**
+- `DOMAIN` - Your domain (e.g., mintel.me)
+- `ADMIN_EMAIL` - SSL certificate contact
+
+**Optional variables:**
+- `REDIS_URL` - Redis connection (default: `redis://redis:6379`)
+- `PLAUSIBLE_DOMAIN` - Analytics domain
+- `PLAUSIBLE_SCRIPT_URL` - Plausible script URL
+
+## 🎯 Performance Optimization
+
+### Redis Caching Strategy
+
+The cache abstraction layer provides:
+
+```typescript
+// Usage in your Astro pages
+import { withCache } from '../utils/cache';
+
+// Cache expensive operations
+const blogPosts = await withCache(
+  'blog:posts',
+  () => fetchBlogPosts(),
+  3600 // 1 hour TTL
+);
+```
+
+**Cache Layers:**
+1. **Memory Cache** - Fast, single instance
+2. **Redis Cache** - Distributed, multi-instance
+3. **Composite Cache** - Auto-fallback Redis → Memory
+
+### Nginx Caching
+
+- **Static assets**: 1 year cache
+- **HTML**: No cache (always fresh)
+- **Gzip/Brotli**: Enabled
+
+### Caddy Benefits
+
+- **Automatic SSL** with Let's Encrypt
+- **HTTP/2** out of the box
+- **Automatic redirects** HTTP → HTTPS
+- **Security headers** configured
+
+## 📊 Analytics Integration
+
+### Plausible Setup
+
+Your existing Plausible instance is already self-hosted. Integration:
+
+1. **Update Analytics.astro** with your Plausible domain:
+   ```astro
+   src="https://plausible.yourdomain.com/js/script.js"
+   ```
+
+2. **Add subdomain** to Caddyfile:
+   ```caddy
+   analytics.mintel.me {
+       reverse_proxy http://YOUR_PLAUSIBLE_SERVER:8000
+   }
+   ```
+
+3. **Track custom events**:
+   ```javascript
+   window.plausible('Page Load', { props: { loadTime: 123 }});
+   ```
+
+## 🔐 Security
+
+### Caddy Security Headers
+```caddy
+header {
+    Strict-Transport-Security "max-age=31536000; includeSubDomains; preload"
+    X-Frame-Options "SAMEORIGIN"
+    X-Content-Type-Options "nosniff"
+    X-XSS-Protection "1; mode=block"
+    Server "mintel"
+}
+```
+
+### Docker Security
+- Non-root user in containers
+- Read-only filesystem where possible
+- Limited capabilities
+
+## 📈 Monitoring & Health
+
+### Health Check Endpoint
+```
+https://mintel.me/health
+```
+Returns: `healthy`
+
+### Docker Commands
+```bash
+# View logs
+docker logs -f mintel-website
+
+# Check Redis
+docker exec -it mintel-redis redis-cli ping
+
+# Restart services
+docker-compose restart
+
+# Update deployment
+docker-compose pull && docker-compose up -d
+```
+
+## 🔄 CI/CD Pipeline Flow
+
+1. **Push to Gitea** → Woodpecker triggers
+2. **Test** → Run smoke tests
+3. **Build** → Create Docker image
+4. **Push** → Registry (optional)
+5. **Deploy** → SSH to Hetzner, pull & restart
+
+## 🚨 Troubleshooting
+
+### SSL Issues
+```bash
+# Check Caddy logs
+docker logs mintel-caddy
+
+# Force certificate renewal
+docker exec mintel-caddy caddy renew
+```
+
+### Redis Connection
+```bash
+# Test Redis
+docker exec mintel-redis redis-cli ping
+
+# Check Redis logs
+docker logs mintel-redis
+```
+
+### Cache Issues
+```bash
+# Clear all cache
+docker exec mintel-redis redis-cli FLUSHALL
+```
+
+## 📦 Dependencies
+
+### Required
+- `ioredis` - Redis client
+- Already have: Astro, React, Tailwind
+
+### Docker Images
+- `nginx:alpine` - Web server
+- `redis:7-alpine` - Cache
+- `caddy:2-alpine` - Reverse proxy
+
+## 🎯 Next Steps
+
+1. ✅ **Configure** environment variables
+2. ✅ **Test** locally with `docker-compose up`
+3. ✅ **Setup** Woodpecker secrets
+4. ✅ **Deploy** to Hetzner
+5. ✅ **Monitor** with Plausible analytics
+
+## 💡 Tips
+
+- **First deployment**: Use manual `deploy.sh` to verify everything works
+- **Updates**: CI/CD handles everything on git push
+- **Rollback**: `docker-compose down && docker-compose up -d` with previous image
+- **Scaling**: Add more web containers, Redis handles distributed cache
+
+---
+
+**Total setup time**: ~30 minutes  
+**Maintenance**: Near zero (automated)  
+**Performance**: Excellent (Redis + Nginx caching)  
+**Analytics**: Privacy-focused (Plausible)

+
+### 2. **CI/CD Pipeline**
+- ✅ Woodpecker `.woodpecker.yml` config
+- ✅ Automatic testing, building, deployment
+- ✅ Slack notifications (optional)
+- ✅ Gitea integration ready
+
+### 3. **Cache Architecture** (Professional DI)
+```
+src/utils/cache/
+├── interfaces.ts        # Contracts
+├── memory-adapter.ts    # In-memory implementation
+├── redis-adapter.ts     # Redis implementation  
+└── index.ts            # Service + Factory
+```
+
+**Usage:**
+```typescript
+// Choose your adapter at construction
+const cache = new CacheService(new RedisCacheAdapter(config));
+// or
+const cache = new CacheService(new MemoryCacheAdapter(config));
+
+// Use it
+await cache.wrap('key', asyncFn, ttl);
+```
+
+### 4. **Clean Analytics Architecture** (Constructor DI)
+```
+src/utils/analytics/
+├── interfaces.ts        # Contracts
+├── plausible-adapter.ts # Plausible implementation
+└── index.ts            # Service + Factory
+```
+
+**Usage:**
+```typescript
+// Choose adapter at construction
+const analytics = new AnalyticsService(new PlausibleAdapter(config));
+
+// Track events
+await analytics.trackEvent('Page Load', { loadTime: 123 });
+await analytics.trackOutboundLink(url, text);
+await analytics.trackSearch(query, path);
+```
+
+**Astro Component:**
+```astro
+---
+import { createPlausibleAnalytics } from '../utils/analytics';
+const analytics = createPlausibleAnalytics({ domain, scriptUrl });
+const adapter = analytics.getAdapter();
+const scriptTag = adapter.getScriptTag?.();
+---
+{scriptTag && <Fragment set:html={scriptTag} />}
+```
+
+### 5. **Deployment Scripts**
+- ✅ `deploy.sh` - Manual deployment
+- ✅ `docker-compose.yml` - Container orchestration
+- ✅ `DEPLOYMENT.md` - Complete documentation
+
+## 🎯 Simple Deployment Flow
+
+### Option A: Manual (5 minutes)
+```bash
+# On Hetzner VM
+git clone your-repo /opt/mintel
+cd /opt/mintel
+echo "DOMAIN=mintel.me" > .env
+echo "ADMIN_EMAIL=admin@mintel.me" >> .env
+./deploy.sh
+```
+
+### Option B: CI/CD (Zero touch)
+```bash
+# On your machine
+git push origin main
+# Woodpecker handles everything
+```
+
+## 📊 Performance Features
+
+| Feature | Implementation | Benefit |

+
+## 🏗️ Architecture (Clean & Decoupled)
+
+**Cache Pattern:**
+```
+Your Code → CacheService → [Redis | Memory]Adapter
+                    ↓
+              CacheAdapter Interface
+```
+
+**Analytics Pattern:**
+```
+Your Code → AnalyticsService → [Plausible]Adapter
+                    ↓
+              AnalyticsAdapter Interface
+```
+
+**Constructor Injection:**
+```typescript
+// Cache - Production
+const cache = new CacheService(new RedisCacheAdapter(config));
+
+// Cache - Development/Testing
+const cache = new CacheService(new MemoryCacheAdapter(config));
+
+// Analytics
+const analytics = new AnalyticsService(new PlausibleAdapter(config));
+```

+   ```
+
+2. **Edit the .env file:**
+   ```bash
+   nano .env
+   ```
+
+3. **Fill in your values** (see below)
+
+## Required Variables
+
+### `DOMAIN`
+Your website domain name.
+```
+DOMAIN=mintel.me
+```
+
+### `ADMIN_EMAIL`
+Email for SSL certificate notifications.
+```
+ADMIN_EMAIL=admin@mintel.me
+```
+
+## Optional Variables
+
+### `REDIS_URL`
+Connection string for Redis cache.
+- **Default**: `redis://redis:6379`
+- **Format**: `redis://host:port`
+- **Example**: `redis://redis:6379`

+### `PLAUSIBLE_DOMAIN`
+Domain for Plausible analytics tracking.
+- **Default**: Same as `DOMAIN`
+- **Example**: `mintel.me`
+
+### `PLAUSIBLE_SCRIPT_URL`
+URL to your Plausible analytics script.
+- **Default**: `https://plausible.yourdomain.com/js/script.js`
+- **Example**: `https://analytics.mintel.me/js/script.js`
+
+## Woodpecker CI/CD Variables
+
+These are only needed if using Woodpecker for automated deployment:
+
+### `DEPLOY_HOST`
+Hetzner server IP address or hostname.
+```
+DEPLOY_HOST=123.45.67.89
+```
+
+### `DEPLOY_USER`
+User for SSH access (usually root).
+```
+DEPLOY_USER=root
+```
+
+### `SSH_PRIVATE_KEY`
+Private key for SSH authentication.
+```
+SSH_PRIVATE_KEY=-----BEGIN OPENSSH PRIVATE KEY-----
+...
+-----END OPENSSH PRIVATE KEY-----
+```
+
+**Generate SSH key if needed:**
+```bash
+ssh-keygen -t ed25519 -C "woodpecker@mintel.me"
+ssh-copy-id root@YOUR_HETZNER_IP
+```
+
+### `SLACK_WEBHOOK` (Optional)
+Slack webhook for deployment notifications.
+```
+SLACK_WEBHOOK=https://hooks.slack.com/services/YOUR/WEBHOOK/URL
+```
+
+## Usage Examples
+
+### Local Development
+```bash
+# Create .env file
+cp .env.example .env
+
+# Edit with your values
+nano .env
+
+# Start services
+docker-compose up
+```
+
+### Production Deployment
+```bash
+# On Hetzner server
+cd /opt/mintel
+
+# Create .env file
+cat > .env << EOF
+DOMAIN=mintel.me
+ADMIN_EMAIL=admin@mintel.me
+REDIS_URL=redis://redis:6379
+PLAUSIBLE_DOMAIN=mintel.me
+PLAUSIBLE_SCRIPT_URL=https://analytics.mintel.me/js/script.js
+EOF
+
+# Deploy
+./deploy.sh
+```
+
+### Woodpecker CI/CD
+1. Go to your Gitea repository
+2. Navigate to Settings → Secrets
+3. Add these secrets:
+   - `DEPLOY_HOST` - Your Hetzner IP
+   - `DEPLOY_USER` - Usually `root`
+   - `SSH_PRIVATE_KEY` - Private key content
+   - `DOMAIN` - Your domain
+   - `ADMIN_EMAIL` - Your email
+   - (Optional) `SLACK_WEBHOOK`
+
+## Security Notes
+
+- **Never commit `.env` file** to git (it's in `.gitignore`)
+- **Keep SSH keys secure** and never share
+- **Use strong passwords** for all services
+- **Enable firewall** on Hetzner server
+
+## Troubleshooting
+
+### Variables not loading
+```bash
+# Check if .env file exists
+ls -la .env
+
+# Check file permissions
+chmod 600 .env
+
+# Verify variables
+cat .env
+```
+
+### Docker Compose not using .env
+```bash
+# Explicitly specify env file
+docker-compose --env-file .env up
+
+# Or check if it's being loaded
+docker-compose config
+```
+
+### Woodpecker secrets not working
+1. Verify secret names match exactly
+2. Check repository settings
+3. Restart Woodpecker agent
+4. Check Woodpecker logs
+
+## Environment-Specific Configurations
+
+### Development
+```bash
+# .env
+DOMAIN=localhost:3000
