Footnotes

Footnotes let you add reference notes without cluttering the main text.

Syntax

Here is a sentence with a footnote.[^1]

[^1]: This is the footnote content.

Named Footnotes

You can use descriptive names instead of numbers:

Markdown was created by John Gruber.[^gruber]

[^gruber]: John Gruber created Markdown in 2004 with Aaron Swartz.

Multi-line Footnotes

Here is a complex footnote.[^complex]

[^complex]: This footnote has multiple paragraphs.

    Indent subsequent paragraphs with 4 spaces.

    You can even add code blocks.

Important Notes

• Footnote definitions can be placed anywhere in the document
• They will always render at the bottom of the page
• Footnotes are auto-numbered regardless of your label
• Not all renderers support footnotes (it's an extension)
• GitHub supports footnotes in Markdown files

Best Practices

• Use footnotes for citations and references
• Keep footnote content concise
• Don't overuse footnotes — they interrupt reading flow

💡 Footnotes are perfect for academic writing, blog posts, and documentation!
