# Set up pull request reviews

Get a Zero Cool review on GitHub pull requests. You need the Admin role and a [GitHub connection](/docs/flows/github).

## Ask your agent

> How do I turn on Zero Cool pull request reviews for my repository?

Ask your agent to guide you through the portal for this task; there is no dedicated CLI command.

## In the portal

1. Open **Settings → Integrations**, then the **PR reviews** section.
2. Select **Enable** next to the repository.
3. Choose **Quotes**: **Every pull request** or **On mention**.
4. With **Every pull request**, set the **Target branches**.
5. Choose **Result posting**: **Link**, **Summary** or **Full report**.
6. Choose the **Minimum GitHub role** that may start a review.
7. For **Block merges**, choose **Off**, **Critical**, **High+**, **Medium+** or **Low+**.
8. Select **Enable PR reviews**.
9. If the dialog asks for updated App permissions, select **Review the request on GitHub**. A GitHub owner approves them.
10. To block merges, require **Zero Cool review** in GitHub branch protection for each target branch.

With **Every pull request**, Zero Cool comments the price of a review on each ready pull request into a target branch.
With **On mention**, a user first comments the review command that the settings dialog shows.
A person with the minimum role ticks **Start this review** in that comment. The review spends the credits that the comment shows.
Zero Cool updates the comment with the result.
**Block merges** is a severity threshold. The **Zero Cool review** check fails for an unaccepted finding at or above that severity.
With **Off**, Zero Cool posts no check.

**Summary** and **Full report** post finding details on the pull request. Use **Link** for a public repository.
To change the settings, select **Edit**. To stop new quotes, select **Disable**.
