How do I get signalk data into node red

[dione]

Hi, good work and good Christmas gift. 
I downloaded the new version and it looks very interesting, and with great news.
I'm at home, and I only have to test four DS18B20 temperature sensors, connected to the resistor.
I set the 1w sensors as:
Environment.inside.engineRoom.temperature
Environment.inside.freezer.temperature
Environment.inside.heating.temperature
Environment.inside.mainCabin.temperature

I can view the temperatures on signalK

I have problems from here   . I do not know node-red. How to configure it? To see the signalk data in nose-red.

sorry for my English

Saludos,
