It is meant to be put at the top of the documentation subpage for templates transcluded onto more than 2,000 pages. For templates transcluded onto more than 100,000 pages, or if the first parameter is set to risk, then a stronger wording is given.

Note: It is normal that some of the links in the message box are red.

{{High-use}}

{{High-use|2=discussion page, or use + notation|info=additional text}}

{{High-use |1= |2= |info= |demo= |form= |expiry= }}

The template can be used as is, and will automatically use bot-updated transclusion counts from subpages of Module:Transclusion_count/data/, when available. It can also take some parameters:

• 1=number of transclusions: (deprecated) The first parameter is either a static number of times the template has been transcluded, or the word "risk" (without quotes) to display "a very large number of" instead of the actual value. This value will be ignored, if transclusion data is available for the current page (generally, for templates with more than 2,000 transclusions).
• 2=discussion page, or use + notation: The second parameter is overloaded. It will cause the number of transclusions to display as "#,###+" instead of "approximately #,###" when set equal to "yes" (without quotes). When used in this manner, values will be rounded down, instead of rounded to the nearest number with the appropriate number of significant figures. When set to any other non-blank value, it will replace the link to the template's talk page to the value of the parameter (for example, 2=WP:VPT will insert a link to WP:VPT),
• |info=<extra information>: When set to non-blank, will insert <extra information> into the template text.
• |demo=<Template_name>: Will use the transclusion count for the template at [[Template:<Template_name>]] instead of detecting what template it is being used on. Capitalization must exactly match the value used in Special:PrefixIndex/Module:Transclusion_count/data/.
• |form=: When set to "editnotice", will display the message using {{editnotice}} instead of {{ombox}}.
• |expiry=: Sets the |expiry= parameter for {{editnotice}}.
• |no-percent=yes: suppresses automatic 'percent of all pages' annotation; 'percent of all pages' annotation is automatically added when template is used in more than 1% of all pages (currently {{NUMBEROFPAGES}} is 61,864,226 pages so 1% is 618,642 pages)

This template is used on approximately 9,140,000 pages, or roughly 15% of all pages. This is a very large number!

The /sandbox and /testcases links are the standard names for such subpages. If those pages are created, then the green /doc box for the template will detect them and link to them in its heading. For instance, see the top of this documentation.

Ahechtbot compiles usage statistics for all templates with 2,000 or more transclusions, using User:Ahechtbot/transclusioncount.py, and writes them to subpages of Module:Transclusion count/data (see Wikipedia:Bots/Requests for approval/Ahechtbot 6). These pages are usually updated every Sunday, but since running the query is resource intensive, it may be delayed or skipped if Wikipedia server usage is high. Important: If a transclusion count is available in Module:Transclusion count/data, any manually input values will be ignored by this template.
