Here is a simple footnote.[^1] A second point needs a longer note.[^bignote]

[^1]: This is the first footnote.

[^bignote]: This is a longer footnote with multiple paragraphs. Subsequent paragraphs must be indented with four spaces or one tab to be included in the same footnote.

1. Add the reference in the text
   • Place a caret and a unique identifier inside square brackets [^1] immediately after the word or sentence you want to note, with no space
   • Identifiers can be numbers or words, but they cannot contain spaces or tabs
   • The rendered output will automatically number them sequentially regardless of the identifier name
2. Add the definition elsewhere
   • Define the footnote using the same identifier, followed by a colon and the footnote text such as [^1]: This is the first footnote.
   • This definition can be placed anywhere in the document, it is commonly placed at the bottom and will render at the end of the output
   • Multiple Paragraphs are possible in a footnote definition by indenting subsequent lines or paragraphs by four spaces or one tab.
   • Formatting within the footnote uses Markdown syntax

While widely supported, footnotes are an extension to the original Markdown syntax and may not work in all implementations
