Wikimedia Commons categories serve as collections of media files on every conceivable topic. They are used by a multilingual community, but the main language used for category names is English - even for categories about non-English topics. Wikidata can make the categories significantly easier to use by providing information relevant to the category in the user's language. This can be done with a single infobox that works for all different topics, which can be easily added to the category providing the category is linked to a Wikidata item through a sitelink. This poster will describe how the infobox works, and how to add it to commons categories.
