LLM-generated documentation is great for LLMs to read so they can code better and/or more efficiently. You can write it manually, but as I've discovered over the decades, humans rarely read documentation anyway. So you'll be spending a lot of time writing good for the bots.

This is odd to hear. All the best programmers I know are actually adamant readers of documentation, how else could you be a good programmer without reading the docs? I will say devs admitting to not reading docs does definitely explain how shit current software is from big tech.
