+With the `cloudflare` component can you keep your Cloudflare records up to date.
+
+The component will run every hour, but can also be started manually by using the service `cloudflare.update_records` under services.
+
+## {% linkable_title Setup %}
+
+You will find your global API key in your Cloudflare account settings.
+
+## {% linkable_title Configuration %}
+
+To use the component in your installation, add the following to your `configuration.yaml` file:
+
+```yaml
+# Example configuration.yaml entry
+cloudflare:
+  email: user@example.com
+  api_key: c2547eb745079dac9320b638f5e225cf483cc5cfdda41
+  zone: example.com
+  records:
