The Docs-as-Code Principle#

Documentation as code means treating documentation the same way you treat source code: stored in version control, reviewed in pull requests, tested in CI, and deployed automatically. The alternative – documentation in a wiki, a Google Doc, or someone’s head – drifts out of sync with the codebase within weeks.

The core workflow: docs live alongside the code they describe (usually in a docs/ directory or inline), changes go through the same PR process, CI builds and validates the docs, and a pipeline deploys them automatically on merge.
