Cloudflare follows a docs-as-code approach to create and publish product documentation in Developer Docs. This involves using Git with a public GitHub repository for tracking changes and handling branching and merging, as well as relying on GitHub Actions and Cloudflare Pages for continuous integration and delivery (CI/CD). The company also accepts external contributions to its documentation through its cloudflare-docs GitHub repository. This approach has helped improve the quality of their documentation over time by leveraging feedback from both internal and external contributors, while ensuring that all changes adhere to their style guide and content strategy.
