This tutorial provides a step-by-step guide for developing a simple To-Do list plugin for Strapi v4, a headless CMS, focusing on making the process accessible for newcomers. It outlines the creation of a plugin content-type for data persistence, customization of the backend, setting creation, and the development of a plugin homepage, including the injection of a React component into the admin interface using the Strapi Design System. The guide emphasizes using the generate CLI command to create various components like APIs, controllers, and plugins, and offers commands for both Yarn and npm. It advises enabling the autoReload feature with the --watch-admin option during development to avoid repeated builds, ensuring a smoother workflow. Once the plugin is developed, building the application will integrate the new plugin into the main navigation, linking to its homepage.
