Set Parameters' node\n4. **Add credentials**: Configure Telegram bot token and SMTP settings in n8n credentials\n5. **Update recipients**: Set Telegram chat ID and email addresses in distribution nodes (14/a and 14/b)\n6. **Dependencies**: First run auto-installs nmap-helper; PrinceXML downloads on PDF conversion\n\nNVD API queries are rate-limited (1 second between requests).
