Description

I was trying to create a project using this package but I realised the API changed and Readme wasn't updated.

Expected behavior

To have a concise documentation

Actual behavior

Documentation with old examples

@carmonac did you ever get this done? pretty sure the docs are up to date now since al the examples I pull from it (express related) work just fine.
