+How to build barebox for Embest RIoTboard
+-----------------------------------------
+
+Using the default configuration:
+
+.. code-block:: sh
+
+ make ARCH=arm imx_v7_defconfig
+
+Build the binary image:
+
+.. code-block:: sh
+
+ make ARCH=arm CROSS_COMPILE=armv7compiler
+
+.. note:: replace ``armv7compiler`` with your ARM v7 cross compiler prefix,
+ e.g.: ``arm-linux-gnueabihf-``
+
+The resulting binary image to be flashed will be ``images/barebox-embest-imx6s-riotboard.img``.
+
+Replacing U-Boot with barebox
+-----------------------------
+
+ 1. Connect to the boards's UART (115200 8N1);
+
+ 2. Turn board's power on;
+
+ 3. Wait ``Hit any key to stop autoboot: 2`` prompt and press any key;
+
+ 4. Upload barebox image to the board via tftp and start it
+
+.. code-block:: none
