+     "This package allows you to get notifications when there is something
+to do (for org mode).
+
+Sometimes, you need a reminder a few days before a deadline, e.g. to buy a
+present for a birthday, and then another notification one hour before to have
+enough time to choose the right clothes.
+
+For other events, e.g. rolling the dustbin to the roadside once per week, you
+probably need another kind of notification strategy.
+
+This package tries to satisfy the various needs.
+
+In order to activate this package, you must add the following code into your
+.emacs or .emacs.d configuration:
+
+@lisp
+(require org-notify)
+(org-notify-start)
+@end lisp")
