Let users post comments via Twitter, Facebook, LinkedIn or the old-fashioned way, by specifying their name, email address and website

1. Install from the Python Package Index:
   pip install socialcomments

2. Add socialcomments to your INSTALLED_APPS list

3. Add the following to your URLconf:
   url(r'^comments/', include('socialcomments.urls'))

4. Run python manage.py syncdb or python manage.py migrate

The SOCIAL_COMMENTS_PROVIDERS tuple sets out the various providers that can be used with Social Comments and their respective settings. Currently this project supports Twitter, Facebook, LinkedIn and a basic name-email-URL combination. The SOCIAL_COMMENTS_PROVIDERS setting should look something like this:

SOCIAL_COMMENTS_PROVIDERS = (
	(
		'socialcomments.providers.twitter.TwitterProvider', {
			'CONSUMER_KEY': '<your customer key>',
			'CONSUMER_SECRET': '<your consumer secret>'
		}
	),
	(
		'socialcomments.providers.facebook.FacebookProvider', {
			'CONSUMER_KEY': '<your customer key>',
			'CONSUMER_SECRET': '<your consumer secret>'
		}
	),
	(
		'socialcomments.providers.linkedin.LinkedInProvider', {
			'CONSUMER_KEY': '<your customer key>',
			'CONSUMER_SECRET': '<your consumer secret>'
		}
	)
)

For Twitter and Facebook you shouldn't need to set a callback URL when creating your app, but you might need to for LinkedIn. The URL is http://example.com/comments/connect/callback/, where "example.com" is your domain, and assuming "comments" is the URL stem you've chosen (you should be able to choose any prefix in your URLconf).
