+# Creating NS record with CRD source
+
+You can create NS records with the help of [CRD source](/docs/contributing/crd-source.md)
+and `DNSEndpoint` CRD.
+
+Consider the following example
+
+```yaml
+apiVersion: externaldns.k8s.io/v1alpha1
+kind: DNSEndpoint
+metadata:
+  name: ns-record
+spec:
+  endpoints:
+  - dnsName: zone.example.com
+    recordTTL: 300
+    recordType: NS
+    targets:
+    - ns1.example.com
+    - ns2.example.com
+```
+
+After instantiation of this Custom Resource external-dns will create NS record with the help of configured provider, e.g. `aws`
