;;; Commentary:
;; This package maintains a menu for visiting files that were operated
;; on recently. When enabled a new "Open Recent" sub menu is
-;; displayed in the "Files" menu. The recent files list is
+;; displayed in the "File" menu. The recent files list is
;; automatically saved across Emacs sessions. You can customize the
;; number of recent files displayed, the location of the menu and
;; others options (see the source code for details).
+;; To enable this package, add the following to your .emacs:
+;; (recentf-mode 1)
