Hi Cheryl,
Open the drop-down menu "Help", click on "Style Guide".
"Stickers" is listed on "People or pages in Styles and Standards".
Clicking on "Stickers" you go to the help page.
At the top of the help page there is:
Help:Stickers
Categories: Styles and Standards | Stickers
Clicking on "Stickers" you go to the category. There is the list of all available templates, one of them is "Descendant".
(I hope that the explanation could be understandable)
