Automated Website Update Alerts

I need a small monitoring tool that checks a specific website for any brand-new content every five minutes and lets me know the moment something appears. The checker should:

• Scrape or pull only the parts of the page where fresh content can surface, avoiding a full download each time to keep it light.
• Run on a schedule of roughly 5-minute intervals (a simple cron job or cloud function is fine).
• Send an alert to both Telegram and my email whenever it detects new material. The alert must include a direct link to the fresh item plus a short snippet so I can see at a glance what changed.

A tidy codebase (Python, Node, or another mainstream language) with clear comments is enough—no heavy UI. Hand over:

1. The working script or small app.
2. A brief README covering setup, how to add or adjust target URLs, and how to plug in my own Telegram bot token and email credentials.
3. A quick test run log or screenshot proving that a notification reaches both channels.

If you’ve built similar website-monitor or change-detection utilities before, point me to them so I can see your approach.
