  ## Documentation review

  The following files require a review from a technical writer:

  * #{docs_paths_to_review.map { |path| "`#{path}`" }.join("\n* ")}

  The review does not need to block merging this merge request. See the:

  - [Technical Writers assignments](https://about.gitlab.com/handbook/engineering/technical-writing/#designated-technical-writers) for the appropriate technical writer for this review.
  - [Documentation workflows](https://docs.gitlab.com/ee/development/documentation/workflow.html) for information on when to assign a merge request for review.
