CMSs were developed to make setup, configuration, updating, and maintenance more accessible, flexible, and scalable over time. They enable nontechnical people to manage the content of a website through a user friendly and easy to use interface.

A CMS enforces content structure through data and visual templates which allow administrators to set rules and boundaries that content authors must follow. This ensures content that is added or modified remains structurally consistent throughout the site.

Popular CMSs have large communities of talented professionals who dedicate their time to improve the code base and develop plugins and other resources that expand technical capacity of the system, as well as the knowledge and abilities of users.
