New Node-Red library: node-red-contrib-blynk-ws

Is there a simple tutorial how to use it? I have no idea how to start, even I am not new in HA or Blynk (but I haven’t done anything new in the last period with blynk since all my new projects are on HA).

I have ESP8266 HVAC control (well not the last version) and I would like to see desired and actual temperature, change the desired temperature and turn the heater on and off in HomeAssistant via NodeRed. Can anyone help me how?
