Enabling others to comment on your posts is a nice to have feature for a blog. Disqus is an online tool which can be used to do this. It is pretty easy to integrate with your Jekyll Site.

Embed the code

First you need to add a variable to the YAML Formatter. I added this to all my posts.

Then embed the JavaScript to the template.

My Disqus Configuration looks like this.

Now you should be able to see a comments section for each post.
