+This default configuration will allow you to start experimenting with the
+buildroot environment for the Orange Pi 2G IOT. With the current configuration
+it will bring-up the board, and allow access through the serial console.
+
+How to build it
+===============
+
+Configure Buildroot:
+
+    $ make orangepi_2g-iot_defconfig
+
+Compile everything and build the SD card image:
+
+    $ make
+
+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
