Download yasnippet and autocomplete and add them to the load path or just simply install them using package.el. After that, add this to your .emacs
First, activate yasnippet.
;;; yasnippet
;;; should be loaded before auto complete so that they can work together
(require 'yasnippet)

;;; auto complete mod
;;; should be loaded after yasnippet so that they can work together
(require 'auto-complete-config)
(add-to-list 'ac-dictionary-directories "~/.emacs.d/ac-dict")
(ac-config-default)
;;; set the trigger key so that it can work together with yasnippet on tab key,
;;; if the word exists in yasnippet, pressing tab will cause yasnippet to
