Simply add the tag <code><nowiki>{{lowercase title}}</nowiki></code> at the beginning of a page (and optionally, at the beginning of its talk page). There are no parameters. The tag will only decapitalize the first letter of the page's name in the title at the beginning of the page. Examples:
{| CLASS="wikitable"
|-
! Page name !! Will display
|-
| [[EBay]], [[IPod]], etc. || eBay, iPod, etc.
|-
| [[Talk:EBay]] || Talk:eBay
|}
== Issues ==
The template does '''not''' work together with other title modification templates: you need to use DISPLAYTITLE directly and make sure it's the last DISPLAYTITLE on the page. For example, to make "Example" italic and lowercase, use <code><nowiki>{{DISPLAYTITLE:''example''}}</nowiki></code>.
When using the template on redirect pages, the template must be moved ''after'' the redirect, since otherwise it will break the redirection. This, however, limits the template to have an effect only when viewing the redirect page directly. Nevertheless, it is still useful in this scenario in order to document the proper capitalization of a term.
== Technical ==
This template wraps the [[Help:Magic words|magic word]] DISPLAYTITLE so that it works automatically in any namespace (main, talk, template, etc.) to decapitalise the first letter of the name of a page it is transcluded on.
