What is Disqus?
Disqus is a free commenting platform that can be integrated with your site to allow users to comment on blog posts.
To get started with Disqus, visit the Disqus site signup page here. The unique Disqus URL you provide during the setup process is your site's short name. Once it is created, simply paste this name in the text box on the Admin > Settings > Integrations section of your site.
