It's good for me, so I've installed it for my Mac by the option below in your link. However, it returns just error. I think because the link: `gitwhy.dev/install` returns 404 page. So, you should check your way to install your own tool. It's a good challenge. Best effort!

Looks interesting -- I'm not a developer, but I think it could be helpful for someone like me to understand the reasoning behind the code that AI is generating!
