Are there any liquid installation steps required to complete the app installation?

• With the new release of the app, no manual placement of any coding is required for installing the application in your store's theme. Just one click installation and user is ready to go. However, for using the Discount code functionality there's a small code which needs to be placed in the "cart-template" or "cart.liquid" file of your theme. Follow the coding guide here.

After installation and options setup what’s the next step?

• You can preview the options on the products where you assigned the options. There is no code to be added to get the options live.
