In this section of the documentation, you'll find guides and references related to Medusa's Commerce Modules.

A Commerce Module provides features for a commerce domain within its service. When you install the Medusa application, all Commerce Modules are available out-of-the-box. The Medusa application exposes their features in its core API routes to clients.

A Commerce Module also defines data models, representing tables in the database. The Medusa Framework and tools allow you to extend these data models to add custom fields.
