If you can't even be bothered to write the README without AI, why should I read it?
It’ll fix up environments, bump versions, fix compiler issues and outdated code, give you a better user interface (or create one to begin with). I usually point to this when people question if AI has productivity benefits, because it’s a massive time saver for me. I have spent hours in the past trying to chase down some obscure platform-specific GCC error on Stack Overflow.
Ideally pay it forward and PR the things you fixed.
