Adding Facebook Comments

Hi, I’m using Illdy theme and I’d like to add Facebook comments manually to my single posts and additionally, remove the default Wordpress comments. I inserted the below code into single.php in my child theme, but it didn’t show up anywhere. Where do I insert the below code? Thanks.

<div class="fb-comments" data-href="" data-width="500" data-numposts="5"></div>

Hello there,

I hope you are doing well today.
