Hugo’s documentation is a great reference and very well articulated. If you are looking for a tutorial and want to grow understanding, a book might be much better. I am the author of Hugo In Action ( https://hugoinaction.com ) and the objective of my book is to introduce the concepts slowly and with a running example for easily trying out.
No its not, and not its not. Hugo it easy to install and/or build, I will give it that. But the documentation has always been poor in my mind, with gaping holes for common uses that are maybe outside of the opinionated "norms".
