Passport: Allow sign up with name and email address? (Local Strategy)

Is there any way to allow a user to register on the local strategy with his password, email and name?
Every example I could find online only use name/password or email/password.

I also searched through the the whole passport documentation, but that documentation isn't helpful at all. It's just one bloated site full of examples.
I just need an list of functions, classes and variables passport uses with explanations what they and every parameter of them do. Every good library has something like that, why can't I find it for passport?

Here are the key parts of my code:

passport.use('local-signup', new LocalStrategy({
    usernameField: 'email',
    passwordField: 'password',
    //are there other options?
    //emailField did not seem to do anything
    passReqToCallback: true // allows us to pass in the req from our route (lets us check if a user is logged in or not)
},
function(req, email, password, done) {
    //check if email not already in database
        //create new user using "email" and "password"
        //I want an additional parameter here "name"
}));

So is passport really that limited? There has to be a way to do this, right?
