Improve "Getting Started/Setup"

[bkchr]

When reading the docs I found the following:

First add ReactiveDOT, along with required packages as dependencies to your React project.

For dumb developers like me, it would be really nice to at least link to some react tutorial or even better, to provide the commands to do this :)

I must admit, the documentation can use a lot of improvements 😅

For this instance, I believe a separate tutorial makes sense, because there are like a bazillion different ways & commands involved in setting up a React application :p

Do you prefer an interactive tutorial, like this for example? Or just something simple like a one-pager with all the basics?
