Docs update: Expanded structure and new sections

We’ve expanded several doc areas to make the platform easier to understand, adopt, and build on. This update brings clearer architecture explanations, a new Product & Help sections, module-level details, and improved guidance for teams working with Mercur and Medusa.

What's changed

Expanded Introduction

The Introduction now gives marketplace teams more context on where Mercur fits in a commerce stack. It explains the role of Mercur as a marketplace framework on top of Medusa and why it's a perfect alternative for rigid SaaS platforms.

Extended Backend Architecture

The Backend Architecture section has been extended with more detail on internal flows and architecture overview. It also clarifies how Mercur’s marketplace engine connects to Medusa’s core through APIs.

New Product Section

A new Product section describes the overall framework structure and how it relates to Medusa. It maps out the core commerce modules, core Infrastructure Modules, and marketplace modules.

Module-Level Documentation

Each module now has a more structured description covering the concept, reference links, data models, and services. This gives developers a single place to understand the module's features and how to use them.

New Help Section

The new Help section outlines how to get assistance when working with Mercur. It includes information on LLM-optimised documentation, MCP tooling, and direct support channels, so teams know where to go when they need guidance or have issues to report.

Another update with an internal guide on how to write and maintain documentation is coming soon!
