 And you're all set! Head over to http://127.0.0.1:4000/ to see your site in action.
 
+
+### Enabling Comments (via Disqus)
+
+Optionally, if you have a Disqus account, you can tell Jekyll to use it to show a comments section below each post.
+
+To enable it, add the following lines to your Jekyll site:
+
+```yml
+disqus: your_disqus_id
+```
+
+You can find out more about Disqus' shortnames [here](https://help.disqus.com/installation/whats-a-shortname).
+
+Comments are disabled by default and will only appear in when adding `comments: true` to that post's YAML Front Matter
