+### RKE System Images
+
+Prior to version `0.1.6`, RKE used the following list of images for deployment and cluster configuration:
+```
+system_images:
+  etcd: rancher/etcd:v3.0.17
+  kubernetes: rancher/k8s:v1.8.9-rancher1-1
+  alpine: alpine:latest
+  nginx_proxy: rancher/rke-nginx-proxy:v0.1.1
+  cert_downloader: rancher/rke-cert-deployer:v0.1.1
+  kubernetes_services_sidecar: rancher/rke-service-sidekick:v0.1.0
+  kubedns: rancher/k8s-dns-kube-dns-amd64:1.14.5
+  dnsmasq: rancher/k8s-dns-dnsmasq-nanny-amd64:1.14.5
+  kubedns_sidecar: rancher/k8s-dns-sidecar-amd64:1.14.5
+  kubedns_autoscaler: rancher/cluster-proportional-autoscaler-amd64:1.0.0
+  flannel: rancher/coreos-flannel:v0.9.1
+  flannel_cni: rancher/coreos-flannel-cni:v0.2.0
+```
+As of version `0.1.6`, we consolidated several of those images into a single image to simplify and speed the deployment process.
+
+The following images are no longer required, and can be replaced by `rancher/rke-tools:v0.1.2`:
+- alpine:latest
+- rancher/rke-nginx-proxy:v0.1.1
+- rancher/rke-cert-deployer:v0.1.1
+- rancher/rke-service-sidekick:v0.1.0
