This is the "BSExtensionInfobox" template. Used mainly for MediaWiki extensions, but also for BlueSpice extensions that don't have a page in the AutoDoc namespace. For AutoDoc extensions, use the template BSExtensionInfo. It should be called in the following format:
{{BSExtensionInfobox |desc= |status= |developer= |type= |compatible= |edition= |category= |active= |license= |docu= }}
