Template:Official website/doc

The purpose of this template is to provide a standard format for labeling links to the official website of an article's main topic.

Basic usage
This template can be used without specifying any parameters, if the "official website" Property (P856) is set in the respective article's Wikidata record. Just add to the article's External links section. If on Wikidata more than one official website is given, the entry tagged with the language being English is automatically preferred.

Advanced usage
Four parameters are available:
 * or  or   is used to specify the URL. If this parameter is omitted, the value of "official website" Property (P856) on Wikidata is used.
 * NOTE: If this parameter is specified and doesn't match "official website" Property (P856) on Wikidata, the page is added to Category:Official website different in Wikidata and Wikipedia for maintenance.
 * If this parameter is specified but the "official website" Property (P856) on Wikidata has not been set, the page is added to Category:Official website not in Wikidata for maintenance.
 * If this parameter is not specified and there is no official website available on Wikidata, the page is added to Category:Official website missing URL.
 * or  is used to reformat the title if "Official website" is not suitable.
 * NOTE: This name should succinctly and accurately describe the external link in relation to the subject. In particular, it should not include the article subject's name as the reader reasonably expects that all external links pertain to the subject.
 * is optionally used if there is a different "official website" for use with Mobile Web devices.
 * is optionally used if the website requires Adobe Flash Player software.
