+Summary
+=======
+
+This README is about U-Boot support for SAMSUNG's/NEXELL's ARM Cortex-A9 based
+S5P4418 SoC. It is based on FriendlyARM's U-Boot v2016.01 for the NanoPi2
+(and other) boards [1].
+
+Currently the following boards are supported:
+
+* FriendlyArm NanoPi2   [2]
+* FriendlyArm NanoPC-T2 [3]
+
+
+Build
+=====
+
+* NanoPi2 and NanoPC-T2
+
+make s5p4418_nanopi2_defconfig
+make
+
+
+Installation
+============
+
+- Download Official-ROMs-SDCard-20190718.7z from [4] (images files for android,
+  friendlyCore and LUbuntu)
+- Use s5p4418-sd-lubuntu-desktop-xenial-4.4-armhf-20190718.img to make a SD-card
+- Use dd in the directory where U-Boot has been built to update U-Boot:
+  (replace <SD-card> with the device used for the SD-card, e.g. sdc)
+  sudo dd seek=3841 if=u-boot.bin of=/dev/<SD-card>
+- Boot the board from this SD-card
+
+The source code for (the used?) LUbuntu 16.04 can be found at [5].
