How to add footnotes to GitHub-flavoured Markdown?

Question

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). 

I am following this guide and I don't think I'm doing anything wrong. Can someone point out my mistake?

Answer 1

Expanding a little bit on the previous answer, you can make the footnote links clickable here as well. First define the footnote at the bottom like this

<a name="myfootnote1">1</a>: Footnote content goes here 

Then reference it at some other place in the document like this

<sup>[1](#myfootnote1)</sup> 

Answer 2

GitHub Flavored Markdown doesn't support footnotes, but you can manually fake it¹ with Unicode characters or superscript tags, e.g. <sup>1</sup>.

¹Of course this isn't ideal, as you are now responsible for maintaining the numbering of your footnotes. It works reasonably well if you only have one or two, though.
