Wolf has a small and simple piece of code ready-made for displaying breadcrumbs:

<?php echo $this->breadcrumbs(); ?>

Put it in your Layout where you want the breadcrumbs to appear.

If you want to use a different separator, do it like this:

<?php echo $this->breadcrumbs('-'); ?>

You can use any symbol you like as the separator (plus, minus, colon, semicolon, etc.), as long as you keep it between the quote marks inside the braces: ('here').

$this->breadcrumbs('\\');
