 ## Production `--decorate-only` option
 
 When changes to the OpenAPI are merged to the default branch of the `github/github` repository, a pull request is automatically opened with the updated dereferenced OpenAPI files. When pull requests are authored by `github-openapi-bot`, a CI test runs the `src/rest/scripts/update-files.js` script with the `--decorate-only` option. The `--decorate-only` option only decorates the dereferenced OpenAPI files, using the existing dereferenced OpenAPI schema files, and checks those changes in to the existing branch. The `--decorate-only` option is only used by a 🤖 and is only used on production dereferenced OpenAPI schema files.
