+Amx, another of my packages, allows you to use alternate completion
+systems like ido for commands in M-x, with enhancements like putting
+your most-used commands at the front of the list. First install
+[amx](https://melpa.org/#/amx) from MELPA, then turn on `amx-mode`:

 ```elisp
-(require 'smex) ; Not needed if you use package.el
-(smex-initialize) ; Can be omitted. This might cause a (minimal) delay
-                  ; when Smex is auto-initialized on its first run.
-(global-set-key (kbd "M-x") 'smex)
-(global-set-key (kbd "M-X") 'smex-major-mode-commands)
-;; This is your old M-x.

-(These directions are the same ones given in the smex README file.)
