Help:Editing
Creating a redirect
You may start a new page with the name you want to direct from (see Help:Starting a new page). You can also use an existing page that you are making inactive as a page by going to that page and using the "edit" tab at the top. In either case, you will be inserting the following code at the very first text position of the Edit window for the page:
#REDIRECT [[pagename]]
where pagename is the name of the destination page. The word "redirect" is not case-sensitive, but there must be no space before the "#" symbol. Any text before the code will disable the code and prevent a redirect. Any text or regular content code after the redirect code will be ignored (and should be deleted from an existing page).
