+# Authenticating outside the cluster
+
+This example shows you how to configure a client with client-go to authenticate
+to the Kubernetes API from an application running outside the Kubernetes
+cluster.
+
+You can use your kubeconfig file that contains the context information
+of your cluster to initialize a client. The kubeconfig file is also used
+by the `kubectl` command to authenticate to the clusters.
+
+## Running this example
+
+Make sure your `kubectl` is configured and pointed to a cluster. Run
+`kubectl get nodes` to confirm.
+
+Run this application with:
+
+    cd out-of-cluster-client-configuration
+    go build -o app .
+    ./app
+
+Running this application will use the kubeconfig file and then authenticate to the
+cluster, and print the number of nodes in the cluster every 10 seconds:
+
+    $ ./app
+    There are 3 pods in the cluster
+    There are 3 pods in the cluster
+    There are 3 pods in the cluster
+    ...
+
+Press <kbd>Ctrl</kbd>+<kbd>C</kbd> to quit this application.
+
+> **Note:** You can use the `-kubeconfig` option to use a different config file. By default
+this program picks up the default file used by kubectl (when `KUBECONFIG`
+environment variable is not set).
