+## Install Instructions
+
+The Dragonboard is unique in the way that it uses and android bootloader to load the OS. This makes it difficult for a few reasons:
+
+1) Requires a very specific partition layout
+2) Typically requires a secondary bootloader (usually little kernel (LK). we use u-boot).
+
+All this makes it difficult to create a disk image that can easily be flashed and booted natively. After some time trying various different configurations this is what I landed on:
+
+#### Flash the .img file to and SD card (dd, rufus, LE disk image tool, etc)
+```
+gunzip LibreELEC-Dragonboard.arm-9.80-devel-20190706164625-ce7dc9b-410c.img.gz
+dd if=LibreELEC-Dragonboard.arm-9.80-devel-20190706164625-ce7dc9b-410c.img of=/dev/sdx bs=4M
+```
+
+ #### Mount the first partition
+ ```
+ mount /dev/sdx1 /mnt (or similar)
+```
+
+#### Mount the squashfs SYSTEM file
+```
+ mount -o loop /mnt/SYSTEM /mnt2 (or similar)
+ ```
+#### Write the u-boot bootloader using fastboot
+
+to write u-boot to the boot partition on the emmc you will need to use fastboot. (NOTE: this will wipe out whatever you have in the boot partition on the emmc and will make it so that OS does not boot anymore).
+
+To enter fastboot mode read the following instructions:
+
+1) While holding the Vol (-) button, power on the DragonBoard™ 410c by plugging it in
+2) Once DragonBoard™ 410c is plugged into power, release your hold on the Vol (-) button.
+3) Wait for about 20 seconds.
+4) Board should boot into fastboot mode.
+```
+fastboot flash boot /mnt2/usr/share/bootloader/u-boot.img
+```
+
+#### Unmount partitions
+```
+umount /mnt2
+umount /mnt
+```
+
+#### Plug SD card into Dragonboard and power on
