-This directory contains the CP/M 3 client tools for CP/NET.  These
-tools work only with the MT011 RCBus module.
+This directory contains the CP/M client components for CP/NET.  These
+components require either the MT011 RCBus module or the Duodyne
+Disk I/O board.
 
 All of these files come from Douglas Miller.  Please refer to
 https://github.com/durgadas311/cpnet-z80 for more information and
 the latest source code.
 
-In general, to use CP/NET on RomWBW, it is intended that you will
-copy all of these files into your user 0 directory.
+The build process packages the client files into .lbr packages
+appropriate for the hardware variations and CP/NET versions.
