Joomla version 3.3

I want to use this extn. for a garment store (no shopping cart).
how do I modify the labels under the product details. The free version is not allowing me to change the details.
for eg.
In the demo data, the category is Television.
then the description labels have TV Systems, refresh rate etc.

I need to change this to cloth, type of garment etc.

Dear customer,

There is a parameters field for each category. You should add your own parameters for the category.
