+Arcturus uCLS1012A SoM
+======================
+
+This tutorial describes how to use the predefined Buildroot
+configuration for the Arcturus uCLS101A SoM platform.
+
+Additional information about the uCLS1012A System on Module can be found at
+https://www.arcturusnetworks.com/products/ucls1012a
+and product support for registered users at
+https://www.arcturusnetworks.com/support
+
+Building
+--------
+
+Return to the top directory <buildrootdir> and execute the following commands.
+
+  make arcturus_ucls1012a_defconfig
+  make
+
+Result of the build
+-------------------
+
+After building, you should obtain this tree:
+
+    output/images/
+    +-- arc-ucls1012a.dtb
+    +-- Image
+    +-- part0-000000.itb
+    +-- rootfs.cpio
+    +-- rootfs.cpio.gz
+    +-- rootfs.tar
+    +-- u-boot.bin
+    +-- ucls1012a.its
+
+Flashing
+--------
+
+You'll need to program the image created by buildroot into the SPI NOR flash.
+
+1. Reboot your module and via the serial console press <escape> to enter the B$
+u-boot shell.
+   From the shell you will need to update four environment variables replacing the
+   IPv4 IP Address with ones that will work with your network and tftp server.
+
+   B$ setenv ipaddr 192.168.1.81
+   B$ setenv serverip 192.168.1.80
+   B$ setenv gatewayip 192.168.1.1
+   B$ setenv netmask 255.255.255.0
+   B$ saveenv
+
+2. Enable tftp server to serve the <buildrootdir>/output/images/ folder.
+
+3. Program the new U-Boot binary (optional)
+    If you don't feel confident upgrading your bootloader then don't do it,
+    it's unnecessary most of the time.
+
+    B$ tftp u-boot.bin
+    B$ run program_uboot
+
+4. Program the ITB image (includes Kernel, DTB and Ramdisk)
+
+    B$ tftp part0-000000.itb
+    B$ run iprogram
+
+5. Booting your new system
+
+    Reboot your system by reset command
+    B$ reset
+
+        or
+
+    B$ run bootcmd
+
+Good Luck !
