# Marbu Customization Module This contract is made to change the look and behavior of a marketplace created with [Komple Playground](https://playground.komple.io) or [Marbu](https://marbu.io). Instead of keeping the customization state in the backend, we keep it in a contract for a total on-chain process. This allows us to have a single source of truth for the customization of the marketplace. This is written as a Komple Framework module and it will be registered in the module registry on each project.
