+## Attend a sig-cli meeting
+
+The best way to get started is to attend [sig-cli](https://github.com/kubernetes/community/tree/master/sig-cli)
+meetings.  The bug scrub is a great place to pick up an issue to work on.
+
+## Checking out the code
+
+### Install golang
+
+Install the latest version of [go](https://golang.org)
+
+### Get a copy of the code
+
+Fork and clone the [kubernetes](https://github.com/kubernetes/kubernetes) repository
+
+```sh
+git clone [email protected]/USER/kubernetes
+cd kubernetes
+```
+
+### Build the binary
+
+Build the binary using `go build`
+
+```sh
+cd cmd/kubectl
+go build -v
+./kubectl version
+```
+
+### Edit the code
+
+The kubectl code is under `staging/src/k8s.io/kubectl`.
+
+- Libraries are under `staging/src/k8s.io/kubectl/pkg`
+- Command implementations are under `staging/src/k8s.io/kubectl/pkg/cmd`
+
+## Learning about libraries
+
+Kubectl uses a number of common libraries
+
+- [cobra](https://github.com/spf13/cobra) -- a golang framework for CLIs
+- [client-go](https://github.com/kubernetes/client-go) -- libraries for talking to the Kubernetes apiserver
+- [api](https://github.com/kubernetes/api) -- Kubernetes types
+- [apimachinery](https://github.com/kubernetes/apimachinery) -- Kubernetes apimachinery libraries
