The tutorial discusses implementing a content management system (CMS) on a Hugo site, specifically for managing restaurant menus. It covers adding the food menu, setting up a headless CMS with Netlify CMS, configuring authentication using Netlify Identity, and integrating an image gallery. The process involves creating a config.yml file to define collections, fields, and media folders, as well as adding routes to the config.toml file to expose the CMS to users. The tutorial also touches on adding a drink menu and setting up the necessary configuration for it. By following these steps, a restaurant can easily manage its menus using a headless CMS, making it easier for the head chef to focus on brewing flavors rather than upgrading the website.
