+# About
+This is a source code of Linux Kernel 3.14 for OpenRex board.
+
+### About OpenRex
+OpenRex is an open source hardware and software project.
+
+
+Website: http://www.imx6rex.com/open-rex/
+
+### More detailed software & hardware manual
+For more detailed instructions about how to prepare software for OpenRex, go to:

+
+# Download source code
+    git clone -b jethro https://github.com/FEDEVEL/openrex-linux-3.14.git
+    cd openrex-linux-3.14
+
+# Install & select cross compiler
+
+### If you do not have any compiler installed (or you are not sure)
+    apt-get install gcc-arm-linux-gnueabihf
+    export CROSS_COMPILE=arm-linux-gnueabihf-
+
+### If you have a compiler installed
+    export CROSS_COMPILE=/opt/freescale/usr/local/gcc-4.6.2-glibc-2.13-linaro-multilib-2011.12/fsl-linaro-toolchain/bin/arm-none-linux-gnueabi-
+
+# Setup Architecture
+    export ARCH=arm
+
+# Build 
+Here are instructions how to compile the source code
+
+### QUAD
+    make clean
+    make imx_v7_defconfig
+    make -j4 zImage imx6q-openrex.dtb
+    cp arch/arm/boot/zImage /tftp/imx6/zImage-imx6q-openrex
+    cp arch/arm/boot/dts/imx6q-openrex.dtb /tftp/imx6/imx6q-openrex.dtb
+
+### SOLO
+    TODO
+
+# Update OpenRex SD card with Linux
+Go to OpenRex board, interrupt uBoot booting process (press any key). Then write following commands:
+
+
+    run update_kernel
+    run update_fdt
+
+
+Then press "RESET" button and wait until it boots up.
+
+
+Note: if you would like to test the kernel without saving it to SD card, go to uBoot and use following commands:
+
+
+    tftp 0x12000000 imx6/zImage-imx6q-openrex; tftp 0x18000000 imx6/imx6q-openrex.dtb;bootz 0x12000000 - 0x18000000
