Courses with 50%+ discounts are logged to Google Sheets and sent as formatted Telegram notifications with instructor, rating, and time-limited offer details.\n\n## Setup steps\n1. Connect your Airtop account (for browser automation)\n2. Update the search URL in \"Create a window\" to match your course interests\n3. Connect Google Sheets and select your tracking spreadsheet\n4. Add your Telegram bot token and chat ID\n5. Adjust the schedule trigger frequency (default: daily at midnight)\n\n\n### Sample sheet:\nhttps://docs.google.com/spreadsheets/d/1JQE5aW11UriY-jtybq9LTXqu-Un3khZuNp7SzSjXnVU/edit?gid=0#gid=0\n"
