The Netlify CMS project aims to keep its documentation site updated by utilizing an open-source library called Markdown Magic, which enables the automatic generation of documentation content from a central repository. To further automate this process, Brian Douglas, the founder of OpenSauced, leveraged AWS Lambda and GitHub webhooks to create a seamless synchronization mechanism between the CMS repository and its documentation site. This setup allows contributors to commit updates without any manual intervention, ensuring that the documentation remains up-to-date and easily accessible.
