Change "Add to Cart" button title to "Order"

I am trying to figure out where I have to go to change the text that comes up for the various buttons associated with the cart. I would rather have "Order" than "Add to Cart". Can someone help me please?

All the texts in HikaShop can be overridden in the config under the tab languages by editing your translation file:
