In a docs-as-code workflow, documentation lives in markdown or a similar format, changes go through pull requests, and a static site generator such as Docusaurus, MkDocs, or Sphinx builds the site on every merge.
The approach matters for docs AI because it produces structured, plain-text source with clear history. Clean markdown chunks well for retrieval, and versioned docs make it possible to keep an AI index in sync with releases.
Docs-as-code also makes AI feedback loops actionable. When a chatbot logs a content gap, the fix is a pull request, reviewed and shipped like any other change.
