Learn the craft of documentation for each step in the software development lifecycle, from understanding your users’ needs to publishing, measuring, and maintaining useful developer documentation. Well-documented projects save time for both developers on the project and users of the software. Projects without adequate documentation suffer from poor developer productivity, project scalability, user adoption, and accessibility. In short: bad documentation kills projects. This new edition has been fully updated and edited taking into account the needs for developers and tech writers today, with new content relating to AI, automation and LLMs. Docs for Developers demystifies the process of creating great developer documentation, following a team of software developers as they work to launch a new product. At each step along the way, you learn through examples, templates, and principles how to create, measure, and maintain documentation—tools you can adapt to the needs of your own organization.
