Improve the readme

I was thinking about making the readme a bit prettier by adding CI checks, version (if added) and/or thing like code quality badges to the readme. Maybe some smaller visual changes too. I'll make a sample of what I think of soon.

We can also record a video explaining the basics and show how to use it.

Sounds awesome, maybe something like a small demo showing what's possible.
