+A13-OLinuXino-MICRO
+
+Intro
+=====
+
+These are open hardware boards, based an the AllWinners A13 SoC.
+
+for more details about the boards see the following pages:
+ - https://www.olimex.com/Products/OLinuXino/open-source-hardware
+ - https://www.olimex.com/Products/OLinuXino/A13/A13-OLinuXino-MICRO/
+
+The following defconfig is available:
+ - olimex_a13_olinuxino_micro_defconfig
+   for the A13-OLinuXino-MICRO board using linux-sunxi kernel
+
+(see http://linux-sunxi.org/Linux_Kernel for more details)
+
+How to build it
+===============
+
+Configure Buildroot:
+
+    $ make olimex_a13_olinuxino_micro_defconfig
+
+Compile everything and build the rootfs image:
+
+    $ make
+
+Result of the build
+-------------------
+
+After building, you should get a tree like this:
+
+    output/images/
+    +-- boot.scr
+    +-- rootfs.ext2
+    +-- rootfs.ext4 -> rootfs.ext2
+    +-- rootfs.tar
+    +-- sun5i-a13-olinuxino-micro.dtb
+    +-- u-boot-sunxi-with-spl.bin
+    +-- u-boot.bin
+    `-- uImage
+
+
+How to write the SD card
+========================
+
+On buildroot root directory call the script make-sdimg.sh :
+
+	sudo board/olimex/a13_olinuxino/make-sdimg.sh output/images /dev/sdX
+
+After that the SD card is ready.
+
+Finish
+======
+
+Eject the SD card, insert it in the A13-OLinuXino board, and power it up.
