Best tutorial

I want to learn about Zettlekasten. I think that is a great method to take notes and create a second Brain, but the problem is that I can't find a great video tutorial about the method. I'm reading the book "How to Take Smart Notes: One Simple Technique to Boost Writing, Learning and Thinking" but I don't know if Is a good start.

So, do you recommend any good video or content creator about Zettlekasten?
