[Feature Request] Readme is confusing

[sdairs]

Describe the feature you'd like to request

We need to improve the README to line up with the starter kit landing page and deploy flow inside the product.

Describe the solution you'd like

The README should start with deploying the Tinybird data project, then Vercel, then discuss the optional steps of using the Loggers.

We should discuss generating fake data with Mockingbird.

We should discuss the Next.js logger and other loggers, to make it clear that the project is language agnostic.

Describe alternatives you've considered
