Kosaku Sato updated the documentation for the-turing-way/the-turing-way repository to modernize data validation guidance and align it with the Frictionless Data ecosystem. Focusing on technical writing and documentation skills, Kosaku transitioned references from the deprecated goodtables.io to current Frictionless Data resources, ensuring users are directed to actively maintained tools. The work involved editing Markdown files to replace outdated links and clarify instructions, improving long-term maintainability and usability of the documentation. While the contribution was limited to a single feature over one month, the update addressed a concrete need for accurate, up-to-date data validation resources within the project’s documentation.
