It's nice to get a comment under a photo or a post to your blog. This is a really good way to find out what your visitors think, engage them and make them willing to come back.

First thing to do is to create Disqus account. You can do it here: https://disqus.com.

To add comments to your portfolio, log in to your User Panel and go to 'Settings'.

Now choose 'Site settings' and scroll down to see 'Comments' section. Enter here your Disqus shortname. You can find out where to find it here.
