 -------------
 
 To use bm.el, put it in your load-path and add the following to your .emacs
-
-    (require 'bm)
-
+```emacs-lisp    
+(require 'bm)
+```
 or
 
-    (autoload 'bm-toggle   "bm" "Toggle bookmark in current buffer." t)
-    (autoload 'bm-next     "bm" "Goto bookmark."                     t)
-    (autoload 'bm-previous "bm" "Goto previous bookmark."            t)
-
+```emacs-lisp
+(autoload 'bm-toggle   "bm" "Toggle bookmark in current buffer." t)
+(autoload 'bm-next     "bm" "Goto bookmark."                     t)
+(autoload 'bm-previous "bm" "Goto previous bookmark."            t)
+```
 
 Configuration:
 --------------
 
 To make it easier to use, assign the commands to some keys.
 
 M$ Visual Studio key setup.
-
-    (global-set-key (kbd "<C-f2>") 'bm-toggle)
-    (global-set-key (kbd "<f2>")   'bm-next)
-    (global-set-key (kbd "<S-f2>") 'bm-previous)
-
+```emacs-lisp
+(global-set-key (kbd "<C-f2>") 'bm-toggle)
+(global-set-key (kbd "<f2>")   'bm-next)
+(global-set-key (kbd "<S-f2>") 'bm-previous)
+```
 Click on fringe to toggle bookmarks, and use mouse wheel to move between them.
-
-    (global-set-key (kbd "<left-fringe> <mouse-5>") 'bm-next-mouse)
-    (global-set-key (kbd "<left-fringe> <mouse-4>") 'bm-previous-mouse)
-    (global-set-key (kbd "<left-fringe> <mouse-1>") 'bm-toggle-mouse)
-
+```emacs-lisp
+(global-set-key (kbd "<left-fringe> <mouse-5>") 'bm-next-mouse)
+(global-set-key (kbd "<left-fringe> <mouse-4>") 'bm-previous-mouse)
+(global-set-key (kbd "<left-fringe> <mouse-1>") 'bm-toggle-mouse)
+```
 If you would like the markers on the right fringe instead of the left, add the following line:
-
-    (setq bm-marker 'bm-marker-right)
-
+```emacs-lisp
+(setq bm-marker 'bm-marker-right)
+```
 If you would like to cycle bookmark in LIFO order, add the following line:
-
-    (setq bm-in-lifo-order t)
-
+```emacs-lisp
+(setq bm-in-lifo-order t)
+```
 If you would like to cycle through bookmarks in *all* open buffers, add the following line:
-
-    (setq bm-cycle-all-buffers t)
-
+```emacs-lisp
+(setq bm-cycle-all-buffers t)
+```
 If you would like to remove bookmark after jump to it by `bm-next` or `bm-previous`:
-
-    (setq temporary-bookmark-p t)
-
+```emacs-lisp
+(setq temporary-bookmark-p t)
+```
 or if you want use this feature in your library:
-
-    (bm-bookmark-add nil nil t)
-
+```emacs-lisp
+(bm-bookmark-add nil nil t)
+```
 If you need org-mode to expand the region containing a bookmark, add the following:
-
-    (add-hook 'bm-after-goto-hook 'org-bookmark-jump-unhide)
-
+```emacs-lisp
+(add-hook 'bm-after-goto-hook 'org-bookmark-jump-unhide)
+```
