 Rainbow-delimiters is a "rainbow parentheses"-like Emacs mode for coloring parentheses, brackets, and braces according to their nested depth. It gives a visual reference for which delimiters match, and what statements are at the same depth - if several statements are at the same level, they will be the same color.

 1. Place rainbow-delimiters.el on your emacs load-path.
 
 2. Compile the file (necessary for speed):
-```lisp
-M-x byte-compile-file <location of rainbow-delimiters.el>
-'''
+    M-x byte-compile-file <location of rainbow-delimiters.el>
 3. Add the following to your dot-emacs/init file:
-```lisp
-(require 'rainbow-delimiters)
-'''
+    (require 'rainbow-delimiters)
 4. Add hooks for modes where you want it enabled, for example:
-```lisp
-(add-hook 'clojure-mode-hook 'rainbow-delimiters-mode)
-'''
+    (add-hook 'clojure-mode-hook 'rainbow-delimiters-mode)
 - To activate rainbow-delimiters mode temporarily in a buffer:
-```lisp
-M-x rainbow-delimiters-mode
-'''
-
+    M-x rainbow-delimiters-mode
 5. When using a dark background, if delimiter colors seem washed out
 you may need to add the following to your dot-emacs and restart:
-```lisp
-(setq-default 'frame-background-mode 'dark)
-'''
+    (setq-default 'frame-background-mode 'dark)

 causing rainbow-delimiters to use its light color scheme on dark
