This module implements the topic cat subsystem, which generates the descriptions and categorization for topical category pages on Wiktionary, i.e. those of the format LANGCODE:LABEL, such as Category:fr:Birds and Category:en:Cities in Georgia, USA; and the corresponding umbrella (language-independent) categories LABEL, such as Category:Birds and Category:Cities in Georgia, USA. It is not to be confused with the poscatboiler subsystem, which handles all other type of categories.

For more information, including an introduction to the topic cat subsystem and a description of how to add or modify categories, see Module:category tree/topic cat/data/documentation.

The data that specifies how particular categories are handled is in Module:category tree/topic cat/data and its submodules.
