Nice and quick tutorial you could reference in the doc

Hello,

This tutorial really helped me : https://wajeeh-ahsan.medium.com/rails-user-authentication-with-devise-and-simple-token-authentication-7beafd1bb863

It's much more detailed than your example here : https://github.com/gonzalo-bulnes/simple_token_authentication/wiki/Initial-Devise-sign-in

Maybe you could use the content and add it to the doc ?

Please note that there is a type in the session controller, line 24 : it's :user not :sign_in
