I am just trying to add footnotes in my GitHub Gist, but it doesn\'t work:
Some long sentence. [^footnote]
[^footnote]: Test, [Link](https://google.com).
Although the question is about GitHub flavored Markdown, I think it's worth mentioning that as of 2013, GitHub supports AsciiDoc which has this feature builtin. You only need to rename your file with a .adoc
extension and use:
A statement.footnote:[Clarification about this statement.]
A bold statement!footnote:disclaimer[Opinions are my own.]
Another bold statement.footnote:disclaimer[]
Documentation along with the final result is here.
