Template:Split/doc

This template accepts four parameters: one mandatory unnamed parameter, one optional unnamed parameter, and two named optional parameters. The mandatory parameter is the suggested structure for the new pages that would be created upon the page split. The optional unnamed parameter specifies any possible requirements that should be met before the page is split. The parameter  specifies a reason that the page should be split, and   allows a talk page to be specified to discuss the split; otherwise, the discussion link defaults to the comment section.
