-It manages huge amounts (up to 10.000 and more) of user defined menu items
+It manages huge numbers of user\-defined menu items efficiently.
-efficiently.
+.P
-.SS Options
+dmenu reads a list of newline\-separated items from stdin and creates a menu.
+When the user selects an item or enters any text and presses Return, their
+choice is printed to stdout and dmenu terminates.
+.P
+.B dmenu_run
+is a dmenu script used by dwm which lists programs in the user's $PATH and
+executes the selected item.
+.SH OPTIONS
