Documentation is so important. I have been treating documentation in the same way I handle code. I found mkdocs works pretty well and integrated with a github job that updates the docs when I commit changes to my main branch. It also allows contributors to correct errors or add helpful instructions to documents. I think I have not paid enough attention to my biases though and like the idea of hiring someone to go through the process. I think my instructions are sound but maybe not so much for a user who is not as familiar as I am. I may not be doing things the optimal way but I have used a lot of documentation over the years and feel what I have done addresses gripes I have had with "Big Tech" provided docs.
