Hi,
I am the author of a little book (really small, smartphone sized, only 4.5"x6") ), it's beginner's level guide, no tricks.
 I've tryed post some pages, hoping that it is appreciated, but I give an error message.
The book is available on Amazon in ebook format and paperback, this is a link to content preview: https://a.co/d/eooNvqf
Feedbacks are welcome.

Bye
Rod Jonshon
