quantity

Hello Master of the Code,
i have only recently started working with eShop. It may be that I am asking useless questions. So I ask for your indulgence. 

I would like to use the given number of products, in 

<input type="text" class="input-small form-control eshop-quantity-value" id="quantity_4" name="quantity[]" value="1">

change. So the "1" in value="1". Is this a setting thing or do I have to do this via changes to the layout/design/eShopTemplate?
Have a nice day!
