# Vale (https://devrel.directory/directory/vale)

Command-line prose linter that enforces a docs style guide in CI; keeps large doc sets consistent.

Checks prose against a style guide as code: adopt packaged rules for the Google or Microsoft style guides or write your own checks in YAML. It runs in CI, editors, and pre-commit hooks, failing builds on violations the way a linter fails on code. How docs teams keep a hundred contributors sounding like one writer.
