{{Language icon/Notes}} is documentation for the many separate language icon templates in Category:Language icons, as many will need the same documentation. Using one template makes updates to the respective pages easier.

Ideally, a bot would be used to add template documentation to the pages in Category:Language icons, and with /doc subpages with the following text:

{{Documentation subpage}}<!-- PLEASE ADD CATEGORIES AND INTERWIKIS AT THE BOTTOM OF THIS PAGE -->
==Usage==
{{Languageicon/Notes}}


<includeonly><!-- CATEGORIES AND INTERWIKIS HERE, THANKS -->
[[Category:Language icons]]
