+# External DNS
+
+See: https://github.com/kubernetes-sigs/external-dns
+
+ExternalDNS allows you to keep selected zones (via --domain-filter) synchronized with Ingresses and Services of type=LoadBalancer and nodes in various DNS providers.
+
+Currently, we are only configured to use CloudFlare.
+
+Docs: https://github.com/kubernetes-sigs/external-dns/blob/master/docs/tutorials/cloudflare.md
+
+Any Ingress that has metatdata.annotions with
+external-dns.alpha.kubernetes.io/hostname: `<something>.${DOMAIN}`
+
+will have Cloudflare records created by External DNS.
