+
+== Introduction
+
+The Aviate plugin enables the management of Coupons, i.e. reusable discounts that can be applied to subscriptions using a redemption code. A coupon can be redeemed by customers when creating or updating a subscription (for example, during an upgrade). 
+
+Coupons provide flexibility to offer fixed-amount or percentage-based discounts and can be scoped to specific plans. They are designed to improve customer acquisition, incentivize upgrades, or manage targeted promotions.
+
+Each coupon includes configurable attributes to control its behavior, such as reusability, discount type, and optional expiration.
+
+== Coupon Attributes
+
+A coupon in Aviate consists of the following attributes:
+
+* `Redemption code`: A unique code that customers can use to apply the discount.
+* `Reusability`: Whether the coupon can be applied multiple times by the same customer.
+* `Discount type`: The discount calculation method:
+** `Fixed`: Applies a fixed monetary amount.
+** `Percentage`: Applies a percentage-based discount.
+* `Discount price`: Amount and currency (valid when `Discount type = Fixed`).
+* `Discount percentage`: Percentage value (valid when `Discount type = Percentage`).
+* `Expiration date`: Optional date after which the coupon can no longer be redeemed.
+* `Plan list`: Optional list of plans for which the coupon is applicable.
+
+== Getting Started with Aviate Coupons
+
+This section provides a step-by-step guide to enable and use the Aviate Coupon functionality.
+
+=== Installing the Plugin
+
+Install the Aviate plugin as described in the https://docs.killbill.io/latest/how-to-install-the-aviate-plugin.html[How to Install the Aviate Plugin] guide.
+

+
+=== Using Coupon APIs
