 - Extends the Laravel HTTP Client to make it straightforward to use. Se the [usage section](#usage) below for examples. 
 - Supports common auth flows like OAuth2 and refresh tokens with most grant types.
 
+#### Vision, roadmap & plans for the future

+I want to support as many common auth flows as possible.\
+If you have a use case that is not super obscure,
