Description:
There is a typo in the Quickstart section of the README file.

django-docker-box/README.md

Line 28 in 385e14a

$ git clone https://github.com/django-docker-box/django-docker-box.git

Currently, it shows:

$ git clone https://github.com/django-docker-box/django-docker-box.git

However, the correct URL should be:

$ git clone https://github.com/django/django-docker-box.git

This should be updated to avoid confusion for users following the setup instructions.
