-Node-RED nodes for Analog Devices' SmartMesh® IP Motes and Manager
+Node-RED nodes for Analog Devices' [DC2274A-A SmartMesh IP USB Network Manager](http://www.analog.com/en/design-center/evaluation-hardware-and-software/evaluation-boards-kits/dc2274a-a.html).
 
-# ALPHA RELEASE
+![DC2274A-A, Motes, RPi Zero WH and CANDY_Pi_Lite](images/DC2274A-A_Motes_RPi_CANDY_Pi_Lite.jpg)
 
-These nodes are NOT YET AVAILABLE via Node-RED palette manager.
+The above picture shows a typical demonstration set including:
+
+- DC2274A-A SmartMesh IP USB Manager dongle
+- SmartMesh Motes containing controllable LED, temperature sensor and GPIO/UART/SPI/I2C interfaces
+- Raspberry Pi Zero WH for running Node-RED/CANDY RED(a custom version of Node-RED)
+- CANDY Pi Lite LTE Board for 4G/LTE mobile connection to upload data/download control commands from cloud servers
+
+## Example Flow
+
+The bundled example flow includes the following operations:
+
+- Turn on/off LED on remote motes
+- Getting LED on/off command results
+- Showing temperature data from remote motes
+- Showing SmartMesh network event notifications
+
+![Example flow](images/example-flow-working.jpg)
+
+## Easy to use
+
+These are provided by the default firmware on the evaluation kit. So you don't have to flash a specific firmware to work the example but just turn all motes on and connect the USB manager to Raspberry Pi, ASUS Tinker Board or other Linux box where Node-RED runs.
+
+## Listing Active Motes
+
+You can find the active (online) motes from the manager dialog while monitoring the flow.
