I’ve found a related (locked) discussion Comprehensive hugo tutorial for beginners? that has (at the time) drawn some attention and participation over a longer period.
I took the time browsing that discussion and found it to be an illuminating read. I confess to not having been able to find out whether the issues raised there have meanwhile been addressed but I fear some, if not many, may still be relevant.
On a side note: it saddens me to find that my opinion has ruffled some feathers. I’ve posted a few questions when I started out with Hugo in late 2014, over at the now-defunct Google Groups repository. I’ve found Hugo illuminati to be extremely helpful and managed to get up & running more or less as advertised. I’m convinced this forum reflects that attitude to an even greater extent, from what I’ve been able to see over the years. Rest assured that I have nothing but the greatest respect for all who selflessly dedicate their valuable time and share their experience and knowledge, here and elsewhere.
