+Intro
+=====
+
+This directory contains a Buildroot configuration for building a
+Pine64 PineCube.
+
+Board homepage: https://www.pine64.org/cube/
+Board wiki:     https://wiki.pine64.org/wiki/PineCube
+
+How to build it
+===============
+
+  $ make pine64_pinecube_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 PineCube and power it up. The console
+is on the serial port 2, 115200 8N1 (check Wiki for board pinout).
