+# Kubernetes Java API Sample Code
+
+This module contains sample code used to show how to use the Kubernetes client Java API.
+
+Before running those samples, make sure that your environment is correctly configured to access
+a working Kubernetes cluster.
+
+An easy way to check that everything is working as expected is issuing any *kubectl get* command:
+
+```shell
+$ kubectl get nodes
+```
+If you get a valid response, then you're good to go.
