Protip: don’t use of using an asterisks for footnotes. There is Markdown syntax for that:

Main[^1] text[^2]

[^1]: First footnote.
[^2]: Second comment.

It gets rendered like this:

Main[^1] text[^2]

[^1]: First footnote. [^2]: Second comment.

Note that the footnotes don’t have to be at the bottom of the comment. You an put each in a paragraph immediately after its usage, and the Markdown renderer will still put them at the bottom.
