Markdown Footnotes

Footnotes in markdown are created using the following syntax:

1This is a sentence with a footnote.[^1]
2
3[^1]: This is the footnote text.

The footnote is referenced by the caret symbol ^ followed by a number or identifier. The identifier can be anything, so long as it is unique within the document. The footnote text is defined at the end of the document, using the same identifier.¹
