Clone this repository, add this to your ~/.emacs file and fill in the appropriate file names:

(add-to-list 'load-path "~/dir/to/cloned/sly")
(require 'sly-autoloads)
(setq inferior-lisp-program "/opt/sbcl/bin/sbcl")

If you wish to byte-compile SLY yourself (not needed generally) you can do

make compile compile-contrib

in the dir where you cloned SLY.
