Integrate league/oauth2-client with laravel (or any oauth client?)

Dear Forum, I was trying to set up a OAuth client in Laravel to consume SalesForce Oauth2. I did try Socialite, but it is not straightforward, even with the Laracast videos.

• Do you have a recommendation of an oauth client for Laravel? or
• Step by step guide on how to implement league/oauth2-client ? or
• Step by step guide on how to implement the SalesForce client for Socialite.

thank you, Alex.
