Module:category tree/derived cat/doc

This module implements {{derived cat}}. The documentation here describes how the module works, and how to add, modify or remove information from the category tree. For information on how to use the template itself, see its documentation.

This module does not use a data module with recognised labels. Instead, the labels are taken directly from Module:languages, Module:families and Module:etymology languages. Thus, any valid language, family or etymology language code is a valid label. For the top-level category, the label ROOT is used.
