Footnote Syntax

You can add comments and references without cluttering the main text. When you create footnotes:

• Superscript numbers with footnotes appear where you add footnote references
• Readers can click the link to jump to the footnote content at the bottom of the page

---

To create footnotes, add symbols and numbers in square brackets []

• The identifier can be numbers and words, but cannot contain spaces and tabs
• The identifier only associates the footnote reference with the footnote itself
• Footnotes are numbered in order
• Footnote content is unique ^Note and ^note are different footnotes

This is a footnote[^1],use to explain the text.
[^1]: This is the footnote content.

Rendered output:

This is a footnote¹,use to explain the text.

Best Practices for Footnotes

Use Descriptive Identifiers

Use descriptive identifiers to make footnotes easier to understand and maintain.

This is a footnote[^important-note],use to explain the text.
[^important-note]: This is the footnote content.

Multiple Footnotes

You can add multiple footnotes in the same document.

This is a footnote[^1],use to explain the text.
This is another footnote[^2],use to explain the text.
[^1]: This is the first footnote content.
[^2]: This is the second footnote content.

Rendered output:

This is a footnote¹,use to explain the text. This is another footnote²,use to explain the text.
