At Open Source Summit Japan 2025, Erin McKean talked about the challenges to producing good project documentation, along with some tooling that can help guide the process toward success. It is a problem that many projects struggle with and one that her employer, Google, gained a lot of experience with from its now-concluded Season of Docs initiative. Through that program, more than 200 case studies of documentation projects were gathered that were mined for common problems and solutions, which led to the tools and techniques that McKean described.
