This is for when you need proper technical documentation, not just a README with install commands and good luck. It treats docs as a product with different page types: quickstarts for the happy path, how-to guides for specific problems, reference pages for dry facts, concept pages for mental models. The workflow forces you to pick the page type first, then build a skeleton, then write. It comes with templates, a house style guide, and a review checklist. Useful if you're maintaining a library or framework and tired of people asking questions that docs should answer, or if you're inheriting a docs site that's half marketing fluff and half stale code samples.
