 ## Configure runners at the organization level
 
 Organization owners can set a default runner type for {% data variables.copilot.copilot_code-review_short %} and {% data variables.copilot.copilot_cloud_agent %} across all repositories in the organization, and control whether individual repositories can override this default.
 
 > [!NOTE]
-> The organization-level runner type applies to both {% data variables.copilot.copilot_code-review_short %} and {% data variables.copilot.copilot_cloud_agent %}. Repositories can still override the organization default using `copilot-setup-steps.yml` unless you disable **Allow repositories to customize the runner type**. For more information, see [AUTOTITLE](/copilot/how-tos/administer-copilot/manage-for-organization/configure-runner-for-coding-agent#preventing-repositories-from-customizing-the-runner-type).
