+pcDuino v1 (http://www.linksprite.com/linksprite-pcduino)
+
+Intro
+=====
+
+This default configuration will allow you to start experimenting with the
+buildroot environment for the LinkSprite pcDuino v1 board including its flavors
+pcDuino-Lite and pcDuino-Lite-WiFi. With the current configuration it will bring-up the
+board and allow access through the serial console as well as ethernet and wireless network interfaces.
+
+How to build it
+===============
+
+Configure Buildroot:
+
+ $ make pcduino_defconfig
+
+Modify Buildroot configuration if needed, e.g. add more packages to target:
+
+ $ make menuconfig
+
+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
