If you want to re-use it, make sure you have changed the
#+properties setting (specifically the
:dir value) to your local preferences.
Everything else should be working with the default settings. I use Emacs v27.1 with Org-Mode v9.3.7 - though it should be working in earlier versions as well.
GitHub specific info:
There's an annoying bug in the
GitHub renderer for Org-Mode files. It does not allow using
#+property constructions to specify global variables for the
src blocks. More specifically, the renderer does not take into account the
:exports both property and the
#+RESULTS blocks will not be rendered. The existing workaround for this is to specifically use
:exports both with every
src block in the document.
