This template is used to display a small flag icon next to a wikilinked country name.  It is related to the {{tl|flagicon}}, {{tl|flagcountry}} and {{tl|flagu}} templates, but offers more options in terms of the text string displayed.

See [[Wikipedia:WikiProject Flag Template]] for the main documentation/discussion page for the flag templates system.

==Usage==
'''<nowiki>{{flag|</nowiki>'''''country identifier'''''&#124;'''''optional variant'''''&#124;'''name=''alternative text string'''''&#124;'''size=''maximum width and/or height of the flag image'''''<nowiki>}}</nowiki>'''

* ''country identifier'' is the common name of the country (e.g. "United States"), a common alias (e.g. "US"), or a standard country code such as those listed at [[ISO 3166-1 alpha-3]]
* ''variant'' is an optional second parameter that can be used to display a flag variation, such as a historical flag.  The list of variants for each country is documented on the appropriate template page, such as [[:Template:Country data Germany]]
* ''alternative text string'', this optional value, specified by the '''name''' parameter, is used to display alternative text
* ''size'', this optional value is specified by the '''size''' parameter, and is used to specify the maximum width and/or height of the flag image. This parameter is specified using standard [[Wikipedia:Extended image syntax|image syntax]].
