## Docs Review

The following files require a review from the Documentation team:

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

When your content is ready for review, mention a technical writer in a separate
comment and explain what needs to be reviewed.

You are welcome to mention them sooner if you have questions about writing or updating
the documentation. GitLabbers are also welcome to use the [#docs](https://gitlab.slack.com/archives/C16HYA2P5) channel on Slack.

Who to ping [based on DevOps stages](https://about.gitlab.com/handbook/product/categories/#devops-stages):
