# Deployment Instructions

## Quick Start on Remote Server

1. Copy the entire 'deploy-package' folder to your remote server
2. On the remote server, navigate to the folder
3. Run these commands:

### For Linux/Mac:
```bash
npm install --production
cp .env.example .env
nano .env  # Edit configuration
npm start
```

### For Windows:
```powershell
npm install --production
Copy-Item .env.example .env
notepad .env  # Edit configuration
npm start
```

4. Access the dashboard at http://your-server-ip:3001

## Keep It Running

### Using PM2 (Recommended):
```bash
npm install -g pm2
pm2 start server/index.js --name resource-monitor
pm2 save
pm2 startup
```

### As a systemd service (Linux):
```bash
sudo nano /etc/systemd/system/resource-monitor.service
```

Add:
```ini
[Unit]
Description=Resource Monitor
After=network.target

[Service]
Type=simple
User=youruser
WorkingDirectory=/path/to/deploy-package
ExecStart=/usr/bin/node server/index.js
Restart=always
Environment=NODE_ENV=production

[Install]
WantedBy=multi-user.target
```

Then:
```bash
sudo systemctl enable resource-monitor
sudo systemctl start resource-monitor
```

## Firewall
Make sure port 3001 is open:
```bash
sudo ufw allow 3001/tcp
```

## Configuration
Edit the .env file to configure:
- Email notifications
- Webhook notifications
- Port number
- Check intervals

Enjoy monitoring your resources! 🎉
