+
+-----
+Intro
+-----
+
+To be able to use your cubieboard board with the images generated by
+Buildroot you have to correctly setup the SD card.
+
+For more information, please see http://linux-sunxi.org/FirstSteps
+
+---------------
+How to build it
+---------------
+
+You need to use the cubieboard_defconfig, to do so:
+ * make cubieboard_defconfig
+
+And to compile:
+ * make
+
+-----------------
+What is generated
+-----------------
+
+After building, you should obtain this tree:
+
+    output/images/
+    +-- rootfs.tar
+    +-- boot.scr
+    +-- script.bin
+    +-- sunxi-spl.bin
+    +-- u-boot.bin
+    `-- uImage
+
+--------------------------
+How setting up the SD card
+--------------------------
+
+Depending on the rootfs size, you might want to use a 2GB or larger SD-card.
+The script mkcubiecard.sh will take care of partitioning and formatting
+the SD-card.
+
+BEWARE! This process will erase your SD card.
+
+Use dmesg to find out where the SD card is attached in the /dev tree
+(<device>) and then:
+
+# sudo ./mkcubiecard.sh <images_dir> <device>
+
+where:
+ - <images_dir> is the directory containing the generated files (usually
+   output/images)
+ - <device> is the device file of the SD card (usually /dev/sdX)
+
