Iconic One – Breadcrumbs

Hi,
1. I’m building out my site myself; and don’t know very much about SEO.
I’m doing the settings/tour of Yoast SEO and have gotten to “breadcrumbs.”
Yoast writes:

If your theme supports my breadcrumbs…..you can change the settings for those here.”

Can anyone tell me whether or not Iconic One theme supports “breadcrumbs?”
2,. If it doesn’t, any opinion on whether adding the coding below is tricky for a beginner, just getting to know HTML?

How to insert breadcrumbs in your theme
Usage of this breadcrumbs feature is explained here. For the more code savvy, insert this in your theme:

<?php if ( function_exists('yoast_breadcrumb') ) {
yoast_breadcrumb('<p id="breadcrumbs">','</p>');
} ?>
