How to insert breadcrumbs into the theme

Hi

I’d really like to add breadcrumbs to my site – but I’m not sure which template to add the code to or where to add it in the file.

I’m using the Yoast WordPress SEO plugin to do this – and the code they’ve told me to put into the template is

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

I’m only using pages on the site – so I’m guessing I need to put it into the Page Template?

Any help or advice would really be appreciated.

Thanks
