+A20-OLinuXino-LIME
+
+Intro
+=====
+
+This is a open hardware board,
+see https://www.olimex.com/Products/OLinuXino/open-source-hardware
+
+See https://linux-sunxi.org/Linux_Kernel, for choosing between
+the legacy linux-sunxi kernel and the device tree / mainline kernel.
+
+
+How to build it
+===============
+
+    $ make olimex_a20_olinuxino_legacy_defconfig
+
+Compile all and build rootfs image:
+
+    $ make
+
+Result of the build
+-------------------
+
+After building, you should get a tree like this:
+
+    output/images/
+    +-- boot.scr
+    +-- rootfs.tar
+    +-- script.bin
+    +-- u-boot-sunxi-with-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 `mksunxicard.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:
+
+    # ./mksunxicard.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)
+
+
+Finish
+======
+
+Eject the SD card, insert it in the A20-OLinuXino-LIME board, and pwer it up.
