MediaWiki User Guide/References
References can be used to cite sources.
To refer to a source in the middle of the text, follow this example:
<ref name="Ref06">Reference text</ref>
or if a named reference has already been used before in the same page:
<ref name="Ref06"/>
To list all the sources referred to in the text, after a second level heading titled "References":
==References== <references/>
