Content Management System
A content management system (CMS) is what allows you to add to or edit your website.
Most of the sites I build are based on WordPress, the world's most popular content management system.

Beaver Builder is very well supported and documented. Numerous resources exist to assist you learn how to use these tools, including my own TheManual.
