Description
[edit]This template was created for guide readers and editors new to the Wikipedia category tree, as well as an indicator for bots trying to figure out which categories diffuse and which ones don't.
This template is especially useful to clarify categories which have ambiguous titles, such as Category:Elcesaites which is a topic category for a movement, not a set category of members of the Elcesaites.
