+;; Ibuffer is an advanced replacement for the `buffer-menu' which is
+;; distributed with Emacs.  It lets you operate on buffers in a
+;; Dired-like way, with the ability to sort, mark by regular
+;; expression, and filter displayed buffers by various criteria.  Its
+;; interface is intended to be analogous to that of Dired.
+;;
+;; To start using it, type `M-x ibuffer'.  If you use it regularly,
+;; you might be interested in replacing the default `list-buffers' key
+;; binding by adding the following to your init file:
+;;
+;;     (global-set-key (kbd "C-x C-b") 'ibuffer)
+;;
+;; See also the various customization options, not least the
+;; documentation for `ibuffer-formats'.
+;;
+;; For more help, type `?' in the "*Ibuffer*" buffer.
