 README
 ^^^^^^
 
-defconfig
-^^^^^^^^^
-The default configuration file, defconfig, performs a
-simple OS test using examples/ostest.  This can be
-configuration as follows:
+Each Neuros OSD configuration is maintained in a sudirectory and
+can be selected as follow:
 
 	cd tools
-	./configure.sh ntosd-dm320
+	./configure.sh ntosd-dm320/<subdir>
 	cd -
 	. ./setenv.sh
 
-netconfig
-^^^^^^^^^
-This alternative configuration file, netconfig, may be used
-instead of the default configuration (defconfig). This
-configuration enables networking using the OSDs DM9000A
-Ethernet interface.  It uses examples/nettest to excercise
-the TCP/IP network.
+Where <subdir> is one of the following:
 
-uipconfig
-^^^^^^^^^
+ostest
+^^^^^^
+This configuration directory, performs a simple OS test using
+examples/ostest.
+
+nsh
+^^^
+Configures the NuttShell (nsh) located at examples/nsh.  The
+Configuration enables both the serial and telnetd NSH interfaces.
+
+nettest
+^^^^^^^
+This alternative configuration directory may be used to
+enable networking using the OSDs DM9000A Ethernet interface.
+It uses examples/nettest to excercise the TCP/IP network.
+
+uip
+^^^
 This configuration file demonstrates the tiny webserver
 at examples/uip.
 
-udpconfig
-^^^^^^^^^
-This alternative configuration file, is similar to netconfig
+udp
+^^^
+This alternative configuration directory is similar to nettest
 except that is use examples/upd to exercise UDP.
 
-These alternative configurations can be selected by (using
-uipconfig as example):
-
-	(Seleted the default configuration as show above)
-	cp config/ntosd-dm320/uipconfig .config
