"Exploring nodes" tutorial missing part

Hi,
doing the tutorials here on the website I noticed that in the second one "Exploring nodes (A pattern example)" the node "group1" is not mentioned at all even though it is shown in the screenshot. I don't know whether if it's stupid or not, but it took me a while to figure out that was the reason why it wasn't working. Somebody should perhaps add it. Thanks for your time.

Seba,

Thanks for pointing this out. Some of the tutorials are a little sloppy about key details like this - very frustrating for beginners.

I will look into this and see if we can do better.

Thanks,

John
