But while we're here, let's take a look at the default frontend - starting with the navbar. It automatically uses your taxonomy structure to create what you see here, so you don't have to hardcode in these paths. Any changes you make to the taxonomy, are reflected immediately here.
While that's easy to manage, maybe you want to handle your navbar differently. Solidus prides itself on being infinitely extensible, so if you'd rather change what's displayed here - or even hardcode it in - it's all good!
