+Acmesystems Arietta board
+============================
+
+This document explains how to set up a basic Buildroot system on the
+Acmesystems Arietta board, whose main site is
+http://acmesystems.it/arietta. Additional details can
+also be found on the tutorial section here http://acmesystems.it/tutorials.
+
+Note that the default Buildroot configuration is prepared to boot from
+an SD card: the first stage bootloader, kernel image and root filesystem
+are all located on the SD card.
+This board comes in to memory sizes: 128 MB and 256 MB.
+
+Configuring and building Buildroot for 128 MB version
+-----------------------------------------------------
+
+  make acme-arietta-128m_defconfig
+  make
+
+Configuring and building Buildroot for 256 MB version
+-----------------------------------------------------
+
+  make acme-arietta-256m_defconfig
+  make
+
+Preparing the SD card
+---------------------
+
+The SD card must be partitioned with at least two partitions: one
+FAT16 partition for the bootloader, kernel image and Device Tree
+blob, and one ext4 partition for the root filesystem. To partition the
+SD card:
+
+  SDCARD=/dev/sdX
+  sudo parted -s $SDCARD mkpart primary fat16 0 32
+  sudo parted -s $SDCARD -- mkpart primary ext2 33 -1
+
+This creates a 32 MB partition for the FAT16 filesystem (type 6) and
+uses the rest for the ext4 filesystem used for the root filesystem.
+
+Then, format both partitions:
+
+  sudo mkfs.vfat -n boot ${SDCARD}1
+  sudo mkfs.ext4 -L rootfs -O ^huge_file ${SDCARD}2
+
+Mount both partitions (if not done automatically by your system):
+
+  sudo mount /dev/${SDCARD}1 /media/boot
+  sudo mount /dev/${SDCARD}2 /media/rootfs
+
+Copy the bootloaders, kernel image and Device Tree blob to the first
+partition:
+
+  cp output/images/at91sam9x5_arietta-sdcardboot-linux-zimage-dt-3.7.bin /media/boot/boot.bin
+  cp output/images/zImage /media/boot/zImage
+  cp output/images/acme-arietta.dtb /media/boot/acme-arietta.dtb
+
+Extract the root filesystem to the second partition:
+
+sudo tar -C /media/rootfs -xf output/images/rootfs.tar
+
+Unmount both partitions:
+
+sudo umount /media/boot
+sudo umount /media/rootfs
+
+Insert your SD card in your Arietta board, and enjoy.
