./lib/secrets.sh create                  # Create encrypted environment
./lib/secrets.sh update DOMAIN example.com  # Update values
./lib/secrets.sh get PUID               # Get values
./lib/secrets.sh list                   # List all keys

# Legacy: Plaintext configuration in ~/homelab/.env
PUID=1000                     # User ID
PGID=1000                     # Group ID
TZ=America/New_York          # Timezone

# Directory Configuration
DATA_ROOT=/mnt/media         # Media storage
CONFIG_ROOT=/opt/appdata     # App configurations

# Security (now auto-generated and encrypted)
DEFAULT_ADMIN_PASSWORD=...   # Generated secure password
DEFAULT_DB_PASSWORD=...      # Database password

# Optional: Custom domain
DOMAIN=yourdomain.com
ACME_EMAIL=admin@yourdomain.com
```

### Service Management Commands
```bash
# NEW: User operations script (runs without sudo)
./user-operations status        # View service status
./user-operations logs <service> # View service logs
./user-operations deploy        # Deploy services
./user-operations stop          # Stop all services

# Legacy: Direct Docker Compose commands
cd ~/homelab
docker compose ps                       # View running services
docker compose logs -f [service-name]  # View logs
docker compose restart [service-name]  # Restart specific service
docker compose pull && docker compose up -d  # Update all services
docker compose down                     # Stop all services
```

### New Architecture
HOPS v3.1.0 introduces a modular architecture with shared libraries:

```

## 🆘 Troubleshooting

### Common Issues

#### Port Conflicts
```bash
# Check for port conflicts
sudo lsof -i :PORT_NUMBER

# View HOPS service status
sudo ./hops.sh
# Select option 4: Service Status
```

#### Service Won't Start
```bash
# Check service logs
cd ~/homelab
docker compose logs [service-name]

# Restart service
docker compose restart [service-name]
```

#### Permission Issues
```bash
# Fix ownership of data directories
sudo chown -R $USER:$USER /mnt/media /opt/appdata
```

### Log Locations
- **Installation Logs**: `/var/log/hops/`
- **Service Logs**: `docker compose logs [service-name]`
- **System Logs**: `journalctl -u docker`

### Getting Help
1. Check the built-in help: `sudo ./hops.sh` → Option 7
2. Review logs in `/var/log/hops/`
3. Verify Docker status: `systemctl status docker`
4. Check service health: `docker compose ps`

## 🔄 Backup and Recovery

### Backup Important Data
```bash
# Backup configurations
sudo tar -czf hops-config-backup.tar.gz /opt/appdata

# Backup compose files
cp ~/homelab/.env ~/homelab/docker-compose.yml /backup/location/
```

### Recovery
```bash
# Restore configurations
sudo tar -xzf hops-config-backup.tar.gz -C /

# Redeploy services
cd ~/homelab
docker compose up -d
```

## 📊 Performance Tuning

### For Low-Resource Systems
- Start with fewer services initially
- Monitor resource usage with Portainer
- Consider using lightweight alternatives (Transmission vs qBittorrent)

### For High-Performance Systems
- Enable GPU transcoding in Jellyfin/Plex
- Use SSD storage for application data
- Configure multiple download clients for redundancy
