This documentation is not using the current rendering mechanism and is probably outdated. The extension maintainer should switch to the new system. Details on how to use the rendering mechanism can be found here.
With this content element you can provide unordered and ordered bullet lists, but also a definition list, in the frontend.
The content is added in the field "Bullet list", where each new line is a new bullet.
Bullet 1 Bullet 2 Bullet 3
For definition lists you use one line for a single definition which starts with the term, followed by the description, separated by a vertical bar "|".
Term 1|Description 1 Term 2|Description 2 Term 3|Description 3
The type of list can be defined with the field "Type of bullets", available in the "Appearance" tab.
