Porting templates

Complex templates are easier obtained from Wikipedia, where considerable work has already gone into developing and debugging these.

Export
Obtain the required XML data via Special:Export. Do not include the full history or the file will become too large. Tick Include templates so that any dependencies are included.

Import
Only administrators of a wiki can use Special:Import. For any templates you require not already on this wiki, make a request at Community noticeboard.

Also include style sheets
Also be sure to copy any relevant styling to MediaWiki:Common.css.

Licensing
Because of CC-BY-SA licensing considerations the previous authors ought to be acknowledged.
