Remember to ALWAYS cite your sources!
If you have a DOI use this template
{{doi|id=}}
For Example
The sun is hot {{doi|id=55.555/j.5555-5555.5555.55555.x}}.
To make an in-text citation use the <ref> tag, followed by the citation and closed with the </ref> tag

To give a footnote a unique identifier, use <ref name="name">. You can then refer to the same footnote again by using a ref tag with the same name. The text inside the second tag doesn't matter, because the text already exists in the first reference. You can either copy the whole footnote, or you can use a terminated empty ref tag that looks like this: <ref name="name" />.
In the following example, the same source is cited three times.
This is an example of multiple references to the same footnote.<ref name="multiple">Remember that when you refer to the same footnote multiple times, the text from the first reference is used.</ref>
Such references are particularly useful when citing sources, if different statements come from the same source.<ref name="multiple">This text is superfluous, and won't show up anywhere. We may as well just use an empty tag.</ref>
A concise way to make multiple references is to use empty ref tags, which have a slash at the end. Although this may reduce redundant work, please be aware that if a future editor removes the first reference, this will result in the loss of all references using the empty ref tags.<ref name="multiple" />

The text above gives the following result in the article (see also section below):

Placing <references /> inserts the full text of all pending inline citations defined by <ref>, anywhere on the page. For example, based on the citations above, the code:
<references />
will yield:
In some language editions of Wikipedia, long reference lists may be placed using the template {{Reflist}}, which incorporates <references />. It provides an optional parameter to display the reference list in multiple columns. For instance, the English, Hindi and Interlingua Wikipedias use the css selector references-small to make the reference text smaller than normal text.
This may be disabled by $wgAllowCiteGroups = false; if desired. However, it is enabled on the foundation wikis.

The anonymous group works as before, while the named group reference will show up as [footnotes 1], and the references will look like this:
