+Intro
+=====
+
+Libre Computer "La Frite" is a low cost SBC based around an Amlogic
+s805x SoC (quad A53), 512MB/1GB DDR4 and a 16MB SPI NOR flash:
+
+https://libre.computer/products/boards/aml-s805x-ac/
+
+How to build it
+===============
+
+Configure Buildroot:
+
+    $ make lafrite_defconfig
+
+Compile everything and build the USB flash drive image:
+
+    $ make
+
+How to write the USB flash drive image
+======================================
+
+Once the build process is finished you will have an image called "usb.img"
+in the output/images/ directory.
+
+Copy the bootable "usb.img" onto a USB flash drive with "dd":
+
+  $ sudo dd if=output/images/usb.img of=/dev/sdX
+
+How to boot
+===========
+
+Insert flash drive to the USB connector furthest away from the IR
+receiver and power up board. The system will boot automatically.
