+Creating bootable SD card:
+==========================
+
+Simply invoke (as root)
+
+sudo dd if=output/images/sdcard.img of=/dev/sdX && sync
+
+Where X is your SD card device.
+
+Booting:
+========
+
+Serial console:
+---------------
+The Cool Pi 4B has a 40-pin GPIO header.
+
+The Uart pins are as follows:
+
+pin 6:  gnd
+pin 8:  tx
+pin 10: rx
+
+Baudrate for this board is 1500000.
+
+Login:
+------
+Enter 'root' as login user, and the prompt is ready.
+
+Network:
+WIFI:     Cool Pi 4B has a aic8800 sdio wifi on board, but
+          aic8800 is not supported by linux mainine yet.
+Ethernet: A RJ-45 interface drivered by PCIE Realtek Ethernet adapter R8169.
+          So we can login it by ssh: ssh root@172.16.12.166
+          Remember to replace you own ip addres on this board.
