+EdgeRouter Lite(edgerouter)
+=====================================
+
+The EdgeRouter Lite is part of the EdgeMax series. It is an MIPS64 router(Cavium Octeon)
+with 512MB of RAM, which uses a USB pendrive for storage.
+
+Setup instructions
+------------------
+
+You will need the following:
+* NFS root setup on your workstation
+* TFTP server installed on your workstation
+* Straight-thru 9-conductor serial cable (DB9, M/F) connected from your 
+  PC to UART1
+* Ethernet connected to the first ethernet port on the board
+
+--- Preparation ---
+
+Build an image (e.g. core-image-minimal) using "edgerouter" as the MACHINE
+
+--- Booting from NFS root ---
+
+Load the kernel, and boot the system as follows:
+
+ 1. Get the kernel (vmlinux) file from the tmp/deploy/images/edgerouter
+    directory, and make them available on your TFTP server.
+
+ 2. Connect the board's first serial port to your workstation and then start up
+    your favourite serial terminal so that you will be able to interact with
+    the serial console. If you don't have a favourite, picocom is suggested:
+
+  $ picocom /dev/ttyS0 -b 115200
+
+ 3. Power up or reset the board and press a key on the terminal when prompted
+    to get to the U-Boot command line
+
+ 4. Set up the environment in U-Boot:
+
+ => setenv ipaddr <board ip>
+ => setenv serverip <tftp server ip>
+
+ 5. Download the kernel and boot:
+
+ => tftp tftp $loadaddr vmlinux
+ => bootoctlinux $loadaddr coremask=0x3 root=/dev/nfs rw rw nfsroot=<nfsroot ip>:<rootfs path> ip=<board ip>:<server ip>:<gateway ip>:<netmask>:edgerouter:eth0:off mtdparts=phys_mapped_flash:512k(boot0),512k(boot1),64k at 3072k(eeprom)
