From a page move: This is a redirect from a page that has been moved/renamed. This page was kept as a redirect to avoid breaking links that may have been made, both internally and externally, to the old article title. This template automatically tags any redirect that results from a page move. For more information, see the category.
From an alternative name: This is a redirect from a title that is another name, a pseudonym, a nickname, or a synonym. It leads to the title in accordance with the naming conventions for common names and can help writing. It is not necessary to replace these redirected links with a piped link.
