Ideas for readme improvements

[Sillyvan]

So i think there could be some additions to the Readme (totally not because i ran into those issues and am not 100% sure how to fix! 😛)

First would be how to make a specific app not depend on build. With frontend stuff it often makes sense to just run vite dev and not build them because there might just be errors somewhere in the app.

Second is how to map ports to apps. In my case i have multiple workers and they all want to launch on the same port. I would say random ports don't fix this either because sometimes you might want to allow certain URLs for something like CORS.

Sadly im not familiar enough with turbo and just to do this myself. But i'm sure it could be helpful for some people!
