+Intro
+=====
+
+This default configuration will allow you to start experimenting with the
+buildroot environment for the Nanopi NEO Plus2. With the current configuration
+it will bring-up the board, and allow access through the serial console.
+
+Nanopi NEO2 link:
+http://nanopi.io/nanopi-neo-plus2.html
+
+Wiki link:
+http://wiki.friendlyarm.com/wiki/index.php/NanoPi_NEO_Plus2
+
+This configuration uses U-Boot mainline and kernel mainline.
+
+How to build
+============
+
+    $ make friendlyarm_nanopi_neo_plus2_defconfig
+    $ make
+
+Note: you will need access to the internet to download the required
+sources.
+
+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 NEO Plus2 and power it up. The console
+is on the serial line, 115200 8N1.
