Adding Components to a Page
Components are the building blocks of content in Adobe® Experience Manager. All content and even templates are built from components. For instance, the text you are reading right now was placed on the page using the generic text component. Other sections in this site go into more depth about what each component does, but they all have one thing in common – they have to be added to a page before they can be set up to display content.
Components can only be added to a particular part of the page that is known as a paragraph system (parSys). Templates define where the parSys lives in a page. A paragraph system is represented with a gray dashed line as seen below.
