Installing django-csp

First, install django-csp via pip or from source:

# pip
$ pip install django-csp

# source
$ git clone https://github.com/mozilla/django-csp.git
$ cd django-csp
$ python setup.py install

Now edit your project’s settings module, to add the django-csp middleware to MIDDLEWARE_CLASSES, like so:

MIDDLEWARE_CLASSES = (
    # ...
    'csp.middleware.CSPMiddleware',
    # ...
)

That should do it! Go on to configuring CSP.
