+  usbnsh:
+  ------
 
+    This is another NSH example.  If differs from other 'nsh' configurations
+    in that this configurations uses a USB serial device for console I/O.
+    Such a configuration is useful on the stm32f429i-disco which has no
+    builtin RS-232 drivers.
+
+    NOTES:
+
+    1. This configuration uses the mconf-based configuration tool.  To
+       change this configuration using that tool, you should:
+
+       a. Build and install the kconfig-mconf tool.  See nuttx/README.txt
+          and misc/tools/
+
+       b. Execute 'make menuconfig' in nuttx/ in order to start the
+          reconfiguration process.
+
+    2. This configuration does have UART1 output enabled and set up as
+       the system logging device.  To use this UART, you must add an
+       external RS-232 line driver to the UART1 pins of the DISCO board
+       on PA9 and PA10 of connector P1.
+
+  usbmsc:
+  ------
+
+    This is an example of enabling the FS OTG port on the DISCO board for
+    mass storage use.  It provides an NSH session on UART1 to allow
+    accessing the connected USB mass storage device.  Such a configuration
+    is useful on the stm32f429i-disco which has no onboard SD card or mass
+    storage solution.
+
+    NOTES:
+
+    1. This configuration uses UART1 as the system console.  To use this
+       UART, you must add an external RS-232 line driver to the UART1 pins
+       of the DISCO board on PA9 and PA10 of connector P1.
+
+    2. The mass storage device will appear as /dev/sda and supports FAT
+       formatted "thumb" flash drives with:
