+**xdeadzone**'s job is to create a window of a specified size and
+position, and prevent the mouse pointer from entering it.
 
 The intended use for it is to keep the mouse out of the "dead zone"
 of a multi-head X display where the monitors don't all have the same
-resolution.
+resolution. When used for this purpose, there will be no visible
+**xdeadzone** window (if there is, you've got the size and/or position
+wrong).
 
 It could also be useful for covering annoying parts of the screen,
 e.g. advertisements in ad-driven software like the Opera browser, or
-Adobe Reader.
+Adobe Reader. Use **-abs** (absolute positioning) mode for this.
+
+When **xdeadzone** is running in a visible part of the screen, it'll
+appear as a solid white rectangle with no title bar or window frame;
+it'll stay on top of other windows; and it will appear on every
+virtual desktop.
+
+**xdeadzone** has been tested with various window managers and desktop
+environments, and works properly with at least: KDE (Plasma 5), XFCE
+4, Fmwv2, WindowMaker, BlackBox, and FluxBox.
