+Buildroot for Embest RIoTboard
+==============================
+
+This is a small development board, based on Freescale IMX6 Solo SoC
+(single core ARM Cortex-A9).
+
+More details about the board can be found at:
+
+  http://www.embest-tech.com/riotboard
+
+1. Compiling buildroot
+----------------------
+
+$ make riotboard_defconfig
+$ make
+
+2. Installing buildroot
+-----------------------
+
+Prepare an SD-card and plug it into your card reader. Always double
+check the block device before writing to it, as writing to the wrong
+block device can cause irrecoverable data loss. Now you can write the
+image to your SD-card:
+
+sudo dd if=output/images/sdcard.img of=/dev/<sdcard-block-device> bs=1M
+
+3. Running buildroot
+--------------------
+
+Position the board so you can read the label "RIoTboard" on the right
+side of SW1 DIP switches. Configure the SW1 swiches like this:
+
+1   0  1   0   0  1   0  1
+ON OFF ON OFF OFF ON OFF ON
+
+Now plug your prepared SD-card in slot J6. Connect a serial console
+(115200, 8, N, 1) to header J18. Connect a 5V/1A power supply to the
+board and enjoy.
