The Elemental module provides the ability for SilverStripe users to break up their page content into pieces. This allows for more targeted control over individual types of content, as well as individual versioning, more detailed reports and easy customisation for developers over how certain pieces of content are presented.
Make sure that your SilverStripe CMS installation has the Elemental module installed, and optionally the SilverStripe Blocks addon module.
We also assume that you have had a developer enable the functionality with configuration before you start.
