User mixin example is not clear

[motatoes]

Adding the mixin to the User model is not clear to me as a django newbie:

• Does it need to be in a custom Auth app in my project?
• Do I need to alter the AUTH_USER_MODEL in the settings.py file?
• Also do I need to perform migrations after this step?

I think this part could be made more clear in the docs.

If you're defining a custom auth model like in the third step, yes, you should add it to AUTH_USER_MODEL. But if you don't already have a custom User model, you can also skip this step as said in the doc.

You're gonna need to migrate after adding simple_email_confirmation since this app has it's own models.
