Benefits of Markdown and Documentation-Driven Development

Technical documentation processes are evolving toward Markdown and integrated workflows to improve synchronization with source code. Using Markdown allows developers to utilize local text editors, perform peer reviews via pull requests, and manage version control more effectively than traditional web-based wiki editors.

Storing documentation alongside code enhances discoverability and ensures that code changes and documentation updates can be submitted simultaneously. In ecosystems like Rust, integrated tools such as doctests—which run example code snippets as part of a test suite—help prevent documentation from becoming outdated or drifting from the actual implementation.
