Usage examples in readme

[smbdelse]

Hello!

I'm wondering if it would be possible to cover in readme some basic usage examples as some starting point. It would make using library a ton easier. Thank you!

Hi @smbdelse,

thanks for the input – I will put something together soon and get back to you when it's done.

This would be great.

It's not immediately clear to me if I can use this plugin to replace postcss-path-replace.
