+## Manually scale kube-dns Deployment
+
+kube-dns creates only one DNS Pod by default. If
+[dns-horizontal-autoscaler](../dns-horizontal-autoscaler/)
+is not enabled, you may need to manually scale kube-dns Deployment.
+
+Please use below `kubectl scale` command to scale:
+```
+kubectl --namespace=kube-system scale deployment kube-dns --replicas=<NUM_YOU_WANT>
+```
+
+Do not use `kubectl edit` to modify kube-dns Deployment object if it is
+controlled by [Addon Manager](../addon-manager/). Otherwise the modifications
+will be clobbered, in addition the replicas count for kube-dns Deployment will
+be reset to 1. See [Cluster add-ons README](../README.md) and
+[#36411](https://github.com/kubernetes/kubernetes/issues/36411) for reference.
+
+## kube-dns addon templates
+
+This directory contains the base UNDERSCORE templates that can be used to
+generate the kube-dns.yaml.in needed in Salt format.
+
+Due to a varied preference in templating language choices, the transform
+Makefile in this directory should be enhanced to generate all required formats
+from the base underscore templates.
+
+**N.B.**: When you add a parameter you should also update the various scripts
+that supply values for your new parameter.  Here is one way you might find those
+scripts:
+
+```
+cd kubernetes && git grep 'kube-dns.yaml'
+```
+
+### Base Template files
+
+These are the authoritative base templates.
+Run 'make' to generate the Salt and Sed yaml templates from these.
+
+```
+kube-dns.yaml.base
+```
+
+### Generated Salt files
+
+```
+kube-dns.yaml.in
+```
+
+### Generated Sed files
+
+```
+kube-dns.yaml.sed
+```
