+* MIPS Creator CI20 *
+*********************
+
+The 'ci20_defconfig' will create a root filesystem and a kernel image
+under the 'output/images/' directory. This document will try to explain how
+to use them in order to run Buildroot in the MIPS Creator CI20 board.
+
+Assuming you are at the U-Boot prompt of the MIPS Creator CI20, you have to
+load the generated kernel image by using the 'tftpboot' command. In
+order to do that, you will need to get the network working. Here you
+have the instructions to set the ip address, netmask and gateway:
+
+ setenv ipaddr x.x.x.x
+ setenv netmask x.x.x.x
+ setenv gatewayip x.x.x.x
+
+Now you have to set the ip for the TFTP server you are going to load the
+kernel image from, and also the name of the kernel image file (we use
+'uImage' as a filename in this example):
+
+ setenv serverip x.x.x.x
+ setenv bootfile uImage
+
+And finally load the kernel image:
+
+ tftpboot
+
+Now you have to extract the generated root filesystem into a USB drive
+or SD-Card. Here you have the instructions to boot from the two of them.
+You have to choose the one your prefer:
+
+From USB
+ setenv bootargs console=ttyS4,115200 console=tty0 mem=256M@0x0
+mem=768M@0x30000000 root=/dev/sda1
+
+From SD-Card
+ setenv bootargs console=ttyS4,115200 console=tty0 mem=256M@0x0
+mem=768M@0x30000000 root=/dev/mmcblk0p1
+
+And finally run this command to boot the board:
+ bootm
