+kubectl-cost is a CLI frontend for Kubecost, a highly accurate provider of
+Kubernetes cluster cost information and optimization opportunities.
+
+kubectl-cost requires Kubecost to be installed in your Kubernetes cluster. Make
+sure to check out the examples and full set of flags (--help) if you have a
+non-default Kubecost install, like running in a custom namespace!
+
+If you don't have Kubecost installed yet, all it takes is Helm and two minutes:
+
+kubectl create namespace kubecost
+helm repo add kubecost https://kubecost.github.io/cost-analyzer/
+helm install \
+    kubecost \
+    kubecost/cost-analyzer \
+    --namespace kubecost \
