+pcDuino v1 boards (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 linksprite_pcduino_defconfig
+
+Modify 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
+
+How to boot new image
+=====================
+
+Insert SD card and reset the board. By default pcDuino board
+boots from SD card.
