Myth:Auth

I'm not sure if this is the right space to talk about support, but I'm not finding another venue.... so feel free to point me in the right direction if available. Just started using CI4, and I'm a little lost in some of the changes still, namespacing is something I haven't gotten into, for example.

So, trying to understand how Myth works is a bit over my head.  I've gone through the Github readme, and I have it installed via Composer, and successfully ran through these steps:

1. Edit app/Config/Email.php and verify that a fromName and fromEmail are set as that is used when sending emails for password reset, etc.
   
   
2. Edit app/Config/Validation.php and add the following value to the ruleSets array: 
   \Myth\Auth\Authentication\Passwords\ValidationRules::class
   
3. Ensure your database is setup correctly, then run the Auth migrations:
   
   php spark migrate -all
   

Now what? I see the generated views under '/app/Views/Auth', and the 'AuthController.php'.
Do I create a new controller extending AuthController, and then copy/paste/override the AuthController methods in my controller?
