Add some documentation to README

It would actually be awesome to have some documentation about how to implement those shiny animations inside an existing project.

We would also love to know how to customize those (using the IsIndeterminate, Thickness and ColorX properties)!

That would be great!

Yes yes yes, all those things are planned and they will be addressed as soon as I can find some time.

For the time being, the MainWindow.xaml file shows several different ways the controls can be customized.

As far as using them in an existing project, there are two options I can think of, off the top of my head :
1. you can copy/paste the files from this repository into an existing project 😢
2. I can look into packaging them in a NuGet package 👍

SO MANY THINGS TO DO

The NuGet package would be great.
