Once the installation script is in place, you can add Kustom Elements to your pages. This guide shows how to use the Payment Method Display element as an example.
Each Kustom Element is an HTML tag. Place it where you want the element to appear. The installation script detects the tag and renders it automatically. Let's integrate a simple element like the kustom-payment-method-display which shows a horizontal list of payment methods.
<kustom-payment-method-display locale="en-SE"></kustom-payment-method-display>and that should be enough to see the payment methods in your store.
