+### Custom Headers
+This annotation is of the form `nginx.ingress.kubernetes.io/custom-headers: custom-headers-configmap` to specify a configmap name that contains custom headers. This annotation uses `more_set_headers` nginx directive.
+
+Example configmap:
+```yaml
+apiVersion: v1
+data:
+  Content-Type: application/json
+kind: ConfigMap
+metadata:
+  name: custom-headers-configmap
+```
+
 ### Default Backend
 
 This annotation is of the form `nginx.ingress.kubernetes.io/default-backend: <svc name>` to specify a custom default backend.  This `<svc name>` is a reference to a service inside of the same namespace in which you are applying this annotation. This annotation overrides the global default backend. In case the service has [multiple ports](https://kubernetes.io/docs/concepts/services-networking/service/#multi-port-services), the first one is the one which will receive the backend traffic.
