+**********
+
+Build
+=====
+
+First, configure Buildroot for your chiliBoard:
+
+  make grinn_chiliboard_defconfig
+
+Build image:
+
+  make
+
+After building you should get a tree like this:
+
+  output/images/
+  ├── am335x-chiliboard.dtb
+  ├── boot.vfat
+  ├── MLO
+  ├── rootfs.ext2
+  ├── rootfs.ext4
+  ├── rootfs.tar
+  ├── sdcard.img
+  ├── u-boot.img
+  └── zImage
+
+Create a bootable microSD card
+==============================
+
+Buildroot prepares a bootable microSD card image "sdcard.img" in output/images/
+directory, To flash SD card just run the following command:
+
+  sudo dd if=output/images/sdcard.img of=/dev/<sd_card> bs=1M
+
+where <sd_card> can be sdX or mmcblkX
+
+*** WARNING! This will destroy all contents of device you specify! ***
+
+Boot chiliBoard
+===============
+
+- insert the microSD card in the microSD slot of the board;
+- plug micro USB cable to provide power and console interface
+- use terminal emulator with 115200 bps, 8n1
