# New CMS Connector API Guide

This document serves as a guide for extending the CMS Connector API to support new Content Management Systems (CMS) and file types. It outlines the process of creating new CMS packages, updating validator and mapper logic, and handling various file extensions and CMS configurations in the /validator route and handleFileProcessing function. The goal is to maintain a modular and CMS-agnostic architecture, allowing for seamless integration of different CMS platforms by following a structured approach for validation, processing, and data mapping.
