How To Start Using Node Red On The Raspberry Pi 

Nice job. Thank you!! FYI to anyone interested, I loaded Node-Red onto my Windows PC following the instructions on the Node-Red site. Not hard at all if you don't have a Raspberry Pi or just want to use a Windows machine.

I am 81 love your style and pace of instruction. That you make no assumptions on what the user knows about the topic already set you apart.
