 You can also install the helm chart from the source code:
 
 To install the eg chart along with Gateway API CRDs and Envoy Gateway CRDs:
 
 ``` shell
-    helm install eg --create-namespace charts/gateway-helm -n envoy-gateway-system
+    make kube-deploy TAG=latest
 ```
 
-## Skip install CRDs
+### Skip install CRDs
 
 You can install the eg chart along without Gateway API CRDs and Envoy Gateway CRDs, make sure CRDs exist in Cluster first if you want to skip to install them, otherwise EG may fail to start:
 
 ``` shell
-    helm install eg --create-namespace charts/gateway-helm -n envoy-gateway-system --skip-crds
+    helm install eg --create-namespace oci://docker.io/envoyproxy/gateway-helm -n envoy-gateway-system --skip-crds
 ```
 
 To uninstall the chart:
 
 ``` shell
     helm delete eg
 ```
