## 🚀 Quick Deployment

### Development
```bash
git clone <repo>
cd readur
docker compose up --build -d
# Access: http://localhost:8000
```

### Production
```bash
# Generate secure secrets
JWT_SECRET=$(openssl rand -base64 64)
DB_PASSWORD=$(openssl rand -base64 32)

# Create .env file
cat > .env << EOF
JWT_SECRET=${JWT_SECRET}
DB_PASSWORD=${DB_PASSWORD}
EOF

# Deploy with production config
docker compose -f docker-compose.prod.yml --env-file .env up -d
```

## 🔧 Key Environment Variables

### Essential (Required for Production)
```bash
JWT_SECRET=your-secure-random-key
DATABASE_URL=postgresql://user:pass@host:port/db
```

### Watch Folder (Network Mounts)
```bash
WATCH_FOLDER=/mnt/nfs/documents
WATCH_INTERVAL_SECONDS=60
FORCE_POLLING_WATCH=1
FILE_STABILITY_CHECK_MS=1000
```

### Performance Optimization
```bash
CONCURRENT_OCR_JOBS=8
MAX_FILE_SIZE_MB=200
MEMORY_LIMIT_MB=2048
OCR_TIMEOUT_SECONDS=600
```

## 🌐 Network Filesystem Examples

### NFS Mount
```yaml
volumes:
  - /mnt/nfs/docs:/app/watch
environment:
  - WATCH_INTERVAL_SECONDS=60
  - FORCE_POLLING_WATCH=1
```

### SMB/CIFS Mount
```yaml
volumes:
  - /mnt/smb/shared:/app/watch
environment:
  - WATCH_INTERVAL_SECONDS=30
  - FILE_STABILITY_CHECK_MS=2000
```

### S3 Mount (s3fs)
```yaml
volumes:
  - /mnt/s3/bucket:/app/watch
environment:
  - WATCH_INTERVAL_SECONDS=120
  - FILE_STABILITY_CHECK_MS=5000
  - FORCE_POLLING_WATCH=1
```
