+# Installing the Client Tools
+
+In this chapter, you will install the command line utilities required to complete this tutorial: [cfssl](https://github.com/cloudflare/cfssl), [cfssljson](https://github.com/cloudflare/cfssl), and [kubectl](https://kubernetes.io/docs/tasks/tools/install-kubectl).
+
+
+## Install CFSSL
+
+The `cfssl` and `cfssljson` command line utilities will be used to provision a [PKI Infrastructure](https://en.wikipedia.org/wiki/Public_key_infrastructure) and generate TLS certificates.
+
+Download and install `cfssl` and `cfssljson` from the [cfssl repository](https://pkg.cfssl.org):
+
+```
+wget -q --show-progress --https-only --timestamping \
+  https://pkg.cfssl.org/R1.2/cfssl_linux-amd64 \
+  https://pkg.cfssl.org/R1.2/cfssljson_linux-amd64
+```
+
+```
+chmod +x cfssl_linux-amd64 cfssljson_linux-amd64
+```
+
+```
+sudo mv cfssl_linux-amd64 /usr/local/bin/cfssl
+```
+
+```
+sudo mv cfssljson_linux-amd64 /usr/local/bin/cfssljson
+```
+
+### Verification
+
+Verify `cfssl` version 1.2.0 or higher is installed:
+
+```
+cfssl version
+```
+
+> output
+
+```
+Version: 1.2.0
+Revision: dev
+Runtime: go1.6
+```
+
+> The cfssljson command line utility does not provide a way to print its version.
+
+## Install kubectl
+
+The `kubectl` command line utility is used to interact with the Kubernetes API Server. Download and install `kubectl` from the official release binaries:
+
+```
+wget https://storage.googleapis.com/kubernetes-release/release/v1.12.0/bin/linux/amd64/kubectl
+```
+
+```
+chmod +x kubectl
+```
+
+```
+sudo mv kubectl /usr/local/bin/
+```
+
+### Verification
+
+Verify `kubectl` version 1.12.0 or higher is installed:
+
+```
+kubectl version --client
+```
+
+> output
+
+```
+Client Version: version.Info{Major:"1", Minor:"12", GitVersion:"v1.12.0", GitCommit:"0ed33881dc4355495f623c6f22e7dd0b7632b7c0", GitTreeState:"clean", BuildDate:"2018-09-27T17:05:32Z", GoVersion:"go1.10.4", Compiler:"gc", Platform:"linux/amd64"}
