Gutenberg is the open-source project that develops the block editor, a modern content creation tool for websites. It is designed for content creators, site builders, and developers who want a more visual and flexible way to construct pages and posts.

• Modular Block System: Content is built using individual blocks for paragraphs, images, galleries, and more. Each block can be moved, styled, and configured independently.
• Live Visual Editing: See your changes in real-time as you build, reducing the need to switch between editing and preview modes.
• Extensible Architecture: Developers can create custom blocks and extend editor functionality using JavaScript and React, integrating new features directly into the editing interface.
• Full-Site Editing Foundation: The project provides the underlying systems for managing site-wide elements like headers, footers, and templates through the same block-based interface.
• Open Development: As a public GitHub project, it allows developers to test upcoming features, report issues, and contribute directly to its ongoing development.
