-Prepare the SD card for the Minnow Board
-========================================
+How to get started with the MinnowBoard (MAX)
+=============================================
 
- 1. Partition the SD card with a GPT partition table
+1. Build
 
-    sudo cgdisk /dev/mmcblk0
+  Apply the defconfig:
 
-    Create two partitions:
+  $ make minnowboard_defconfig
 
-     a) First partition of a few dozens of megabytes, which will be
-        used to store the bootloader and the kernel image. Type must
-        be EF00 (EFI partition).
+  Or, for the Minnowboard MAX board:
 
-     b) Second partition of any size, which will be used to store the
-        root filesystem. Type must be 8300 (Linux filesystem)
+  $ make minnowboard_max_defconfig
 
- 2. Prepare the boot partition
+  Add any additional packages required and build:
 
-    We will format it, mount it, copy the EFI data generated by
-    Buildroot, and the kernel image.
+  $ make
 
-    sudo mkfs.vfat -F 32 -n boot /dev/mmcblk0p1
-    sudo mount /dev/mmcblk0p1 /mnt
-    sudo cp -a output/images/efi-part/* /mnt/
-    sudo cp output/images/bzImage /mnt/
-    sudo umount /mnt
+2. Write the SD card
 
- 3. Prepare the root partition
+  The build process will create a SD card image in output/images.
+  Write the image to an mSD card, insert into the MinnowBoard
+  and power the board on.
 
-    We will format it, mount it, and extract the root filesystem.
+  $ dd if=output/images/sdcard.img of=/dev/mmcblk0; sync
 
-    sudo mkfs.ext3 -L root /dev/mmcblk0p2
-    sudo mount /dev/mmcblk0p2 /mnt
-    sudo tar -C /mnt -xf output/images/rootfs.tar
-    sudo umount /mnt
+  The system starts two consoles: one on the serial port
+  and one on HDMI.
 
- 4. Enjoy
+3. Enjoy
