+### Configuring the runner type for {% data variables.product.prodname_dependabot %}
+
+You can configure which type of runner {% data variables.product.prodname_dependabot %} uses to scan for version and security updates. By default, {% data variables.product.prodname_dependabot %} uses standard **{% data variables.product.company_short %}-hosted runners**. You can configure {% data variables.product.prodname_dependabot %} to use **self-hosted runners** with custom labels, which allows you to integrate with existing runner infrastructure such as {% data variables.product.prodname_actions_runner_controller %} (ARC).
+
+> [!NOTE]
+> * For security reasons, {% data variables.product.prodname_dependabot %} uses {% data variables.product.company_short %}-hosted runners for public repositories, even when you configure labeled runners. 
+> * Labeled runners **do not work** for public repositories.
+
+To configure the runner type:
+
+1. Under "{% data variables.product.prodname_dependabot %}", next to "Runner type", select {% octicon "pencil" aria-label="Edit runner type" %}.
+1. In the "Edit runner type for {% data variables.product.prodname_dependabot %}" dialog, select the runner type you want {% data variables.product.prodname_dependabot %} to use:
+   * **Standard {% data variables.product.company_short %} runner**.
+   * **Labeled runner**: If you select this option, {% data variables.product.prodname_dependabot %} will use self-hosted runners that match the label you specify.
+1. If you selected **Labeled runner**:
+   * In "Runner label", enter the label assigned to your self-hosted runners. {% data variables.product.prodname_dependabot %} will use runners with this label. By default, the `dependabot` label is used, but you can specify a custom label to match your existing runner infrastructure.
+   * Optionally, in "Runner group name", enter the name of a runner group if you want to target a specific group of runners.
+1. Click **Save runner selection**.
