+===== Installation =====
+==== Base tarball ====
+Given ''kubernetes.tar.gz'':
+<code>
+$ tar xzf kubernetes.tar.gz
+</code>
+then script runs:
+  * ''download_kube_binaries''
+  * ''create_cluster''
+==== download_kube_binaries() ====
+Invokes ''get-kube-binaries.sh'':
+<code>
+# Use the script from inside the Kubernetes tarball to fetch the client and
+# server binaries (if not included in kubernetes.tar.gz).
+function download_kube_binaries {
+  (
+    cd kubernetes
+    if [[ -x ./cluster/get-kube-binaries.sh ]]; then
+      # Make sure to use the same download URL in get-kube-binaries.sh
+      KUBERNETES_RELEASE_URL="${KUBERNETES_RELEASE_URL}" \
+        ./cluster/get-kube-binaries.sh
+    fi
+  )
+}
+</code>
+==== create_cluster() ====
+Invokes ''kube-up.sh'':
+<code>
+function create_cluster {
+  if [[ -n "${KUBERNETES_SKIP_CREATE_CLUSTER-}" ]]; then
+    exit 0
+  fi
+  echo "Creating a kubernetes on ${KUBERNETES_PROVIDER:-gce}..."
+  (
+    cd kubernetes
+    ./cluster/kube-up.sh
+    echo "Kubernetes binaries at ${PWD}/cluster/"
+    if [[ ":$PATH:" != *":${PWD}/cluster:"* ]]; then
+      echo "You may want to add this directory to your PATH in \$HOME/.profile"
+    fi
+    echo "Installation successful!"
+  )
+}
+</code>
+==== cluster/get-kube-binaries.sh ====
+<code>
+KUBE_ROOT=$(cd $(dirname "${BASH_SOURCE}")/.. && pwd)
+KUBE_VERSION=$(cat "${KUBE_ROOT}/version")
+CLIENT_PLATFORM="linux"
+CLIENT_ARCH="amd64"
+SERVER_TAR="kubernetes-server-${SERVER_PLATFORM}-${SERVER_ARCH}.tar.gz"
+CLIENT_TAR="kubernetes-client-${CLIENT_PLATFORM}-${CLIENT_ARCH}.tar.gz"
+</code>
+Result:
+<code>
+Will download kubernetes-server-linux-amd64.tar.gz from https://dl.k8s.io/v1.10.0
+Will download and extract kubernetes-client-linux-amd64.tar.gz from https://dl.k8s.io/v1.10.0
