This example demonstrates how to use a custom backend to render custom error pages.
+If you are using Helm Chart, look at [example values](https://github.com/kubernetes/ingress-nginx/blob/main/docs/examples/customization/custom-errors/custom-default-backend.helm.values.yaml) and don't forget to add [configMap](https://github.com/kubernetes/ingress-nginx/blob/main/docs/examples/customization/custom-errors/custom-default-backend-error_pages.configMap.yaml) to your deployment, otherwise continue with [Customized default backend](#customized-default-backend) manual deployment.
+
## Customized default backend
First, create the custom `default-backend`. It will be used by the Ingress controller later on.
