 Configuring the _ExternalDNS_ provider should be done via the `provider.name` value with provider specific configuration being set via the `provider.<name>.<key>` values, where supported, and the `extraArgs` value. For legacy support `provider` can be set to the name of the provider with all additional configuration being set via the `extraArgs` value.
 See [documentation](https://kubernetes-sigs.github.io/external-dns/#new-providers) for more info on available providers and tutorials.
 
-### Provider Example
-#### Setting Up ExternalDNS with CloudFlare
-To deploy ExternalDNS configured for the CloudFlare DNS provider, begin by creating a Kubernetes secret to securely store your CloudFlare API key. This key will enable ExternalDNS to authenticate with CloudFlare:
-```shell
-kubectl create secret generic cloudflare-api-key --from-literal=apiKey=YOUR_API_KEY
-```
-Ensure to replace YOUR_API_KEY with your actual CloudFlare API key.
-
-Next, create a values.yaml file to configure ExternalDNS to use CloudFlare as the DNS provider. This file should include the necessary environment variables:
-```shell
-provider: 
-  name: cloudflare
-env:
-  - name: CF_API_KEY
-    valueFrom:
-      secretKeyRef:
-        name: cloudflare-api-key
-        key: apiKey
-  - name: CF_API_EMAIL
-    value: "[email protected]"
-```
-Replace [email protected] with the email associated with your CloudFlare account.
-
-Finally, install the ExternalDNS chart with Helm using the configuration specified in your values.yaml file:
-```shell
-helm upgrade --install external-dns external-dns/external-dns --version 1.14.4 --values values.yaml
-```
-This command will configure ExternalDNS to manage DNS records using CloudFlare, based on resources present in your Kubernetes cluster.
