== Usage ==
Simply add the [[Help:Wikitext|wikitext]] markup {{tlx|Lowercase title}} at the beginning of a page (and optionally, at the beginning of its talk page). The markup will only decapitalize the first letter of the page's name in the title at the beginning of the page by default.

Some examples (in different [[Wikipedia:Namespace|namespaces]]):

{| class="wikitable" width=370px
|-
! scope="col" | Page name
! scope="col" | Will display
|-
! scope="row" | [[EBay]]
| eBay
|-
! scope="row" | [[Talk:EBay]]
| Talk:eBay
|-
! scope="row" | [[:Category:MacOS]]
| Category:macOS
|-
! scope="row" | [[:Template:IPhone models]]
| Template:iPhone models
|}

== Issues ==
The template cannot be directly combined with other title modification templates, including {{tlx|Italic title}}, {{tlx|Italic disambiguation}}, and {{tlx|Italic title prefixed}}; if more than one of these is placed on a page, only the last is applied, and a [[Template:DISPLAYTITLE#Instructions|DISPLAYTITLE error message]] is generated. Some of these combined stylizations (a lowercased title combined with an italicized title, disambiguation, or both) can be enacted using this template's parameters, as shown in the second table below, while others (a lowercase title with a delayed or otherwise non-standard italicized substring or other modifications not pertaining to case or italicization) require the use of {{tlx|DISPLAYTITLE}} directly.

When using the template on redirect pages, the template must be placed ''after'' the redirect, as it will break the redirection if placed before it. This, however, limits the template to have an effect only when viewing the redirect page directly. Nevertheless, it is still useful in this scenario to document the proper capitalization of a term.

When using the template on other templates, make sure to wrap it with <code><nowiki><noinclude></nowiki></code> tags to prevent it from affecting pages that the other templates are transcluded onto.

== Technical ==
This template wraps the [[Help:Magic words|magic word]] DISPLAYTITLE so that it works automatically in any namespace (main/article, talk, template, category, etc.) to decapitalise the first letter of the name of a page it is transcluded on.

<syntaxhighlight lang=sql>
/* Page using a lowercase title, with or without {{lowercase}} */
SELECT page_title, pp_value AS displaytitle
FROM page
JOIN page_props ON pp_page=page_id AND pp_propname="displaytitle"
WHERE page_namespace=0
AND CONVERT(pp_value USING utf8mb4) COLLATE utf8mb4_bin /* &#greek; */
    REGEXP "^([_ :]+|<[^<>]+>)*([[:lower:]]|&#9[4-6][0-9];)"
</syntaxhighlight>
