Is there any training / online course for node red?

Hi, i have seen somethings in udemy, but i was wondering if anyone knows a good online training in order to get a more structured learning path. I have seen millions of tutorials in youtube, but im seeking for a more structured path!

I recommend watching this playlist: Node-RED Essentials. The videos are done by the developers of node-red. They're nice & short and to the point. You will understand a whole lot more in about 1 hour. A small investment for a lot of gain.

GREAT Thx!!!! Im already starting!
