=== If you have import rights on the new wiki  ===

#Go to [[Special:Export]] on the original wiki. Enter the name of the template in the big text box, check "Include templates" and click Export. This will download a .xml file. 
#Go to [[Special:Import]] on the new wiki and upload the .xml file. 
#Look for CSS classes (like class="foobar") in the template text. If those classes appear in "MediaWiki:Common.css" or "MediaWiki:Monobook.css" on the original wiki, copy them to "MediaWiki:Common.css" on the new wiki. 
#If the template uses [[Help:Magic words#Parser_functions|ParserFunctions]], you have to install the {{mediawiki|Extension:ParserFunctions|ParserFunctions extension}}.
