-Package cmd provides one stop shopping for a command line executable to bind the correct flags,
-build the client config, and create a working client. The code for usage looks like this:
+Package clientcmd provides one stop shopping for building a working client from a fixed config,
+from a .kubeconfig file, from command line flags, or from any merged combination.
 
-    clientBuilder := clientcmd.NewBuilder(clientcmd.NewDefaultAuthLoader())
-    clientBuilder.BindFlags(cmds.PersistentFlags())
-    apiClient, err := clientBuilder.Client()
+Sample usage from merged .kubeconfig files (local directory, home directory)
+	loadingRules := clientcmd.NewKubeConfigLoadingRules()
+	// if you want to change the loading rules (which files in which order), you can do so here
+
+	configOverrides := &clientcmd.ConfigOverrides{}
+	// if you want to change override values or bind them to flags, there are methods to help you
+
+	kubeConfig := clientcmd.NewNonInteractiveDeferredLoadingKubeConfig(loadingRules, configOverrides)
+	kubeConfig.Client()
