Extending and developing emailuser is best done through the included example django project.
Using pipenv:
$ cd example_project
$ pipenv install --ignore-pipfile
(django-emailuser) $ python manage.py migrate
(django-emailuser) $ python manage.py createsuperuser
(django-emailuser) $ python manage.py runserver
(django-emailuser) $ python manage.py createsuperuser
(django-emailuser) $ python manage.py runserver
The default Django system with emailuser app is accessible at:
