cd (go to your user root)
rm -rf .emacs.d (remove existing Emacs config, if any)
git clone git@github.com:SirObi/emacs-python.git .emacs.d
Launch Emacs and run:
M-x jedi:install-server
It's best to cd to the folder you want to open with Emacs and then
emacs .
open -a Emacs.app .
You can alias either to e . in you shell config file (like .zshrc or .bashrc).
