+Intro
+=====
+
+This default configuration will allow you to start experimenting with the
+buildroot environment for the Nanopi R2S. With the current configuration
+it will bring-up the board, and allow access through the serial console.
+
+Nanopi R2S link:
+https://www.friendlyarm.com/index.php?route=product/product&path=69&product_id=282
+
+This configuration uses ATF, U-Boot mainline and kernel mainline.
+
+How to build
+============
+
+    $ make friendlyarm_nanopi_r2s_defconfig
+    $ make
+
+Note: you will need access to the internet to download the required
+sources.
+
+Files created in output directory
+=================================
+
+output/images
+
+├── bl31.elf
+├── boot.vfat
+├── extlinux
+├── idbloader.img
+├── Image
+├── rk3328-nanopi-r2s.dtb
+├── rootfs.ext2
+├── rootfs.ext4 -> rootfs.ext2
+├── rootfs.tar
+├── sdcard.img
+├── u-boot.bin
+└── u-boot.itb
+
+How to write the SD card
+========================
+
+Once the build process is finished you will have an image called "sdcard.img"
+in the output/images/ directory.
+
+Copy the bootable "sdcard.img" onto an SD card with "dd":
+
+  $ sudo dd if=output/images/sdcard.img of=/dev/sdX
+  $ sudo sync
+
+Insert the micro SDcard in your Nanopi R2S and power it up. The console
+is on the serial line, 1500000 8N1.
+
+Notes
+=====
+
+This configuration can also be used to drive the Friendlyarm Nanopi Neo3 board.
