That's funny, I had the opposite experience. When I found out that info was the GNU projects recommended way of documentation, I was all on board. Then I tried using it, and it couldn't find most CLI software I used. So I downloaded the texinfo archives… and that still lacked probably 50% of the commands I tried to look up.

Then I searched up how to get info pages for this or that tool, and someone on StackOverflow had said that it was woefully incomplete and outdated at this point.

I think I'll give it another try and report back
