When an article is large, it often has a summary and a link to a main article. This template is used after the heading of the summary, to indicate a link to the subtopic article that has been summarized.
1, 2, 3, ... – the pages to link to. If no page names are specified, the current page name is used instead (without the namespace prefix). Categories and files are automatically escaped with the colon trick, and links to sections are automatically formatted as page § section, rather than the MediaWiki default of page#section.
l1, l2, l3, ... orlabel 1, label 2, label 3, ... – optional labels for each of the pages to link to (this is for articles where a piped link would be used). Note that the extra parameters use a lower case 'L', for example, l1, notL1.
selfref – if set to "yes", "y", "true" or "1", adds the CSS class "selfref". This is used to denote self-references.
extraclasses - any extra CSS classes to be added.
category - If set to "no", "n", "false", or "0", suppresses the error tracking category. This has an effect only if the leftmost parameter (the hatnote text) is omitted.
