Documentation for supported python and Django version is outdated

[browniebroke]

Missing Django 1.11 and Python 3.6 at least. https://opbeat.com/docs/articles/get-started-with-django/#supported-django-and-python-versions

Not sure if you still support as far back as Django 1.4? I tried to look into this repo, but this doc appears to be maintained somewhere else.

Anyway, I thought I'd report this small documentation issue.
