To install them, you need to have MELPA in your package-archives. You can add it by evaluating the following elisp code:

(add-to-list 'package-archives
             '("marmalade" . "http://marmalade-repo.org/packages/") t)

Setup

Put the following elisp code on your emacs setup:

(setq lean-rootdir "~/projects/lean")
(setq-local lean-emacs-path
            (concat (file-name-as-directory lean-rootdir)
                    (file-name-as-directory "src")
                    "emacs"))
(add-to-list 'load-path (expand-file-name lean-emacs-path))
(require 'lean-mode)
