  <h4>minikube troubleshooting</h4>
  <p>If your minikube environment does not boot correctly:</p>
  <ol>
  <li>Minikube requires an OS virtualization back-end</li>
  <li>Most OSes include some support for virtualization</li>
  <li>You can use the <a href="https://github.com/kubernetes/minikube#quickstart"><code>--vm-driver</code></a> flag to select a specific virt provider</li>
  </ol>
  <pre><code contenteditable>minikube start --vm-driver=virtualbox</code></pre>
  <p>Check the project <a href="https://github.com/kubernetes/minikube#requirements"><code>README</code></a> for more information about <a href="https://github.com/kubernetes/minikube#requirements">supported virtualization options</a></p>

  <h3>rkt-powered minikube (optional)</h3>
  <p>To start <code>minikube</code> with <code>rkt</code> enabled, try:</p>
  <pre><code contenteditable>minikube start --network-plugin=cni --container-runtime=rkt</code></pre>
  <p>to verify:</p>
  <pre><code contenteditable>minikube ssh
docker ps # expect no containers here

  <h3>install the docker cli</h3>
  <p>Download and install binary from <a href="https://store.docker.com/search?offering=community&type=edition">"the docker store"</a></p>
  <p>Or, use a package manager to install:</p>
  <pre><code contenteditable>brew install docker</code></pre> 
  <p>To verify <code>docker</code> availability:</p>
  <pre><code contenteditable>docker version</code></pre>
  <p>To <a href="https://github.com/kubernetes/minikube#reusing-the-docker-daemon">reference minikube's docker daemon from your host</a>, run:</p>

  <section id='go'>
  <h5><b>ADVANCED CHALLENGE OPTION</b></h5>
  <h3>install go (optional)</h3>
  <p>Download and install binary from <a href="https://golang.org/doc/install">golang.org</a></p>
  <p>Or, use a package manager to install:</p>
  <pre><code contenteditable>brew install go
