 # ctlptl
-Making local Kubernetes clusters fun and easy to set up
+
+Want to mess around with Kubernetes, but don't want to spend an ocean on
+hardware?
+
+Maybe you need a `ctlptl`.
+
+## What is ctlptl?
+
+`ctlptl` (pronounced "cuddle puddle") is a CLI for declaratively setting up
+local Kubernetes clusters.
+
+Inspired by `kubectl` and
+[ClusterAPI's](https://github.com/kubernetes-sigs/cluster-api) `clusterctl`, you
+declare your local cluster with YAML and use `ctlptl` to set it up.
+
+## Why did you make this?
+
+At [Tilt](https://tilt.dev/), we want to make Kubernetes a nice environment for local dev.
+
+We found ourselves spending too much time helping teams debug misconfigurations in their dev environment.
+
+We wrote docs like [Choosing a local dev
+cluster](https://docs.tilt.dev/choosing_clusters.html) and example repos like
+[kind-local](https://github.com/tilt-dev/kind-local),
+[minikube-local](https://github.com/tilt-dev/minikube-local), and
+[k3d-local](https://github.com/tilt-dev/k3d-local) to help people get set up.
+
+`ctlptl` is a culmination of what we've learned.
+
+## How do I try it?
+
+We're still writing it! Stay tuned.
