	:::info
	📌 This feature requires the installation of the [Gateway API bundle](https://gateway-api.sigs.k8s.io/guides/#installing-a-gateway-controller) and passing an
	additional flag to the cert-manager controller.
	To install v1.5.1 Gateway API bundle (Gateway CRDs and webhook), run the following command:
	```sh
	kubectl apply -f "https://github.com/kubernetes-sigs/gateway-api/releases/download/v1.0.0/standard-install.yaml"
	```
	Since cert-manager 1.15, the Gateway API support is no longer gated behind a
	feature flag, but you still need to enable the Gateway API support.
	To enable the Gateway API support, use the [file-based
	configuration](../installation/configuring-components.md#configuration-file) using the
	following `config` Helm value:
	```yaml
	config:
	apiVersion: controller.config.cert-manager.io/v1alpha1
	kind: ControllerConfiguration
	enableGatewayAPI: true
	```
	The corresponding Helm command is:
	```sh
	helm upgrade --install cert-manager oci://quay.io/jetstack/charts/cert-manager --namespace cert-manager \
	--set config.apiVersion="controller.config.cert-manager.io/v1alpha1" \
	--set config.kind="ControllerConfiguration" \
	--set config.enableGatewayAPI=true
	```
	The Gateway API CRDs should either be installed before cert-manager starts or
	the cert-manager Deployment should be restarted after installing the Gateway API
	CRDs. This is important because some of the cert-manager components only perform
	the Gateway API check on startup. You can restart cert-manager with the
	following command:
	```sh
	kubectl rollout restart deployment cert-manager -n cert-manager
	```
