Want to use Yoast Breadcrumbs

There are a lot of posts about using Yoast breadcrumbs but most of those topics are closed and I didn’t find a solution.

I want to add this code from Yoast:
<?php
if ( function_exists(‘yoast_breadcrumb’) ) {
yoast_breadcrumb( ‘<p id=”breadcrumbs”>’,'</p>’ );
}
?>

Right now breadcrumbs are enabled in Enfold. One solution said to go to functions.php and replace the Enfold breadcrumb code with something else. I use the Child theme and couldn’t find any breadcrumb code to replace.

Please let me know the best way to implement the Yoast breadcrumb code. Should I just add it to the child theme functions.php?

Thanks!
