Woocommerce Tabs Child theme

Hello.

I”m looking for any help on adding and editing the tabs in my product page.
http://docs.woothemes.com/document/editing-product-data-tabs/

This is the info i have.

We’ve taken over this project made by someone else. And my coder is saying that he needs to make a child theme in order to do it. Is this normal? or correct? Or does anyone know how to do it as is with no child theme and They’ve been successful Editing or adding tabs.

The tabs are currently below the product image and they say additional info. I’d like to change the name and add. http://www.xshelmets.com/shop/helmets/classic-skate/

Any info would be helpful. 🙂

Thanks
