How to add link in same post

This should work now.
It’s using the markdown footnotes synthax. e.g.

Here is a footnote reference,[^1] and another.[^2]

[^1]: Here is the footnote.

[^2]: Here's number two.

Will show as:

Here is a footnote reference,[1] and another.[2]


  1. Here is the footnote. ↩︎

  2. Here’s number two. ↩︎
