I recently switched to Spacemacs and I'm really enjoying it. If you're a Vim user who wants to try Emacs, or an Emacs user who wants to work faster I recommend trying it.
Pardon my ignorance but just running `git clone --recursive http://github.com/syl20bnr/spacemacs ~/.emacs.d` would install it? Wouldn't I need a working Emacs installation first? If yes, which one should I install for a Mac?
