Add output from the example in the README.md

[william76]

Heya,

It might be nice to show in the README.md file the output from the example shown and not just the example itself.

This is the first place someone might look when browsing around tools and libraries. It would be handy to see an example of what the result of using the tool is and not just the decorations without having to dig into the docs to find one 😉

Anyways... just my $0.02
