that recommend to use
(require 'org-install)
However org-install itself says:
;; The file org-install is obsolete.
;;
;; It is provided here so that (require 'org-install) does not
;; trigger an error for users with obsolete Emacs configuration.
;; You can safely remove (require 'org-install) from your config."
And contains nothing else!!
So what exactly is the case?
What is the setup procedure recommended for git-installed org?
