I do not understand what this is exactly, but I'm very interested! What is a LaTeX "extension" ? Is it a LaTeX package that will allow me to write my math directly in unicode ? That would be so cool!

Could you please clarify the documentation (add some context) so that it is understandable to LaTeX users? Especially to LaTeX users that will want to keep using their own editor, and do not want to touch Atom with a long stick...

I meant extension in sence that it's a LaTeX language extension to it's superset.

There's no LaTeX package and I myself will not port it. SugarTeX is Pandoc/Markdown oriented project in the first place.

You can use it as a command line prepocess text filter though. It should work as long as you use ˎ or ˎˎ to define SugarTeX.

You can already write your mathematics directly in Unicode, without needing any additional LaTeX package. See e.g. https://tex.stackexchange.com/q/87257/48 and the questions in the "Linked" sidebar on the right. (You may have to declare a few things one time; there are examples in the linked questions.) This thing here is only relevant if you're using Markdown and Pandoc, AFAICT.
