Footnotes

Plugin: markdown-it-footnote

Use footnotes when you need to provide additional information without complicating the text. Footnotes consist of two parts linked by labels:

• a reference in the document text, displayed as a superscript;
• a block of additional information. Usually placed at the end of the document.

Here's a simple footnote,[^1] and here's a longer one.[^bignote]

[^1]: This is the first footnote.

[^bignote]: Here's one with multiple paragraphs and code.

You can vote for footnote support in YFM by default in GitHub issues.
