:''ISO'' — [[ISO 3166-1 alpha-3]] country code
:''IOC'' — [[List of IOC country codes|IOC country code]]
:''FIFA'' — [[List of FIFA country codes|FIFA country code]]
If any of the three codes are not applicable for a particular country, leave the respective parameters blank.
This template is placed on the flag template itself (similar to how the {{tl|documentation}} template is placed). This template depends on the mandatory existence of a /doc subpage, which is only used to transclude interwiki links.
