# Overview

The functionality included in each add-on is defined by a combination of features and their configurations, referred to in Stigg as [**entitlements**](../../../managing-customers-and-subscriptions/entitlements/overview).

Add-ons support two types of entitlements:

* **Feature entitlements** — grant access or usage limits for [boolean](./boolean), [configuration](./configuration), or [metered](./metered) features.
* **[Credit entitlements](./credits)** — grant a recurring amount of credits to customers on a set cadence (monthly or yearly).
