New and improved Workers Docs

Cloudflare has announced significant updates to its Workers Docs, including reorganization of content into four categories for easier navigation, improved formatting with more structure and detail, redesigned pages with new UI components, accurate search functionality, and the addition of dark mode. The updated documentation aims to provide a better developer experience and make it more approachable for beginners. These improvements will also be applied to other Cloudflare products' documentation in the future.
