Hugo’s documentation site is poor. WordPress installation is a beast and involves getting PHP, Apache, and MySQL installed, which are each nontrivial. Hugo only seems more intimidating than WordPress because of the size of the documentation gap.
Yeah, I'd agree with that. Even when just setting up the Disqus comments the other day I found the docs lacking. This would probably be less of an issue making Hugo config changes was something I did more than a couple of times per year.
