 Packages represent the individual products you want to serve a customer on your Paywall. You don’t necessarily need to display every package that’s available in your Offering, and some templates may only support displaying one or a limited number of packages, so be sure to choose a template that reflects the options you want to offer your customers.
 
+The templates above that support multiple packages allow you to select a package name which will be displayed when this package is being shown. Below is a small explanation of each option that you can choose from:
+
+- Subscription duration in months - The duration in months of the package selected (I.E. 12 months for Annual, 6 months, 1 month, etc...)
+- Offer Period (Monthly, Annual, Etc...) - The name of the period selected when configuring the package in RevenueCat. So in this case, if you selected "Monthly" as your option when creating the package and putting the products into the package, then Monthly would be displayed as the package name in your paywall. If you choose Custom when configuring the package, the product identifier will show instead.  
+- Product Name - The name of the product configured in RevenueCat.

 For templates that support multiple packages, you should select packages in the order that you’d like them to display. Then, you can separately choose which package should be preselected for your customers by default.
