+     "This package implements a menu that lists enabled minor-modes, as well
+as commonly but not currently enabled minor-modes.  It can be used to toggle
+local and global minor-modes, to access mode-specific menus, and to get help
+about modes.
+
+This menu is intended as a replacement for the incomplete yet wide list of
+enabled minor-modes that is displayed in the mode line by default.  To use the
+menu like this, enable Minions mode.
+
+Alternatively the menu can be bound globally, for example:
+@code{(global-set-key [S-down-mouse-3] 'minions-minor-modes-menu)}.")
