References

The basic concept of the <ref> tag is that it inserts the text enclosed by the ref tags as a footnote in a designated section.
The following code must be placed behind the text that you want to place a reference behind. The reference in many cases is a text with a link to an external web page.

<ref>[url text]</ref>

You can also make footnotes in this way. In that case the code is:

<ref>text</ref>

In both cases the code will generate a numbered link behind the text.

You also need to make a section where the references are placed, like this:

== References ==

<references />

Or like this:

<references />

For multiple use of the same citation or footnote, you can also use the named references feature, choosing a name to identify the citation, and typing

<ref name="Something">text of the citation</ref> Thereafter, the same footnote may be reused any number of times by typing just

<ref name="Something" />

Note: The References section is commonly placed below 'See also' and above 'External links.'
