Footnotes can be useful to reference detailed information without breaking the flow of your document. Footnotes create a small superscript link in your text that brings the user to the footnote information at the bottom of the page.
Examples¶
Example 1¶
Scientists have found evidence that dolphins call each other by "name". [^1] Research has revealed that the marine mammals use a unique whistle to identify each other.

Example 2¶
Even Leonhard Euler, the greatest mathematician ever, was not flawless. He once conjectured
> at least n nth powers are required to sum to an $n$th power, for n > 2
In 1996, a counterexample proved this to be false. [^counterexample]
[^counterexample]: $27^5 + 84^5 + 110^5 + 133^5 = 144^5$
