+Lichee RV dock
+===============
+
+Lichee RV Dock is a RISC-V Linux development kits with high integration, small
+size and affordable price designed for opensource developer. It's equipped with
+HDMI interface and it supports many screen by its screen convert board. It's
+also equipped with many peripherals, including a UAB-A port, 2.4G Wifi-BT module,
+an analog microphone and a speaker jack interface.
+
+How to build
+============
+
+$ make lichee_rv_dock_defconfig
+$ make
+
+Wifi
+==========
+
+Edit board/lichee_rv/overlay_dock/etc/wpa_supplicant.conf or
+/etc/wpa_supplicant.conf once connected to the board:
+
+* Replace YOURSSID with your AP ssid
+* Replace YOURPASSWD with your AP password
+
+Bluetooth
+==========
+
+To make the device discoverable and pairable, once connected to the board:
+
+* bluetoothctl power on
+* bluetoothctl discoverable yes
+* bluetoothctl pairable yes
+
+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
+
+Connect a TTL UART to the debug connector, insert the microSD card and
+plug in a USB-C cable to the PWR connector to boot the system.
