-## Upgrade TensorFlow Plugin
+## Code Example
+To build a TFJob with: 
+10 workers with restart policy as failed and 2 CPU and 2Gi Memory
+1 ps replica with resources the same as task defined resources
+1 chief replica with resources the same as task defined resources and restart policy as always
+run policy as clean up all pods after job is finished.
+
+You code:
+```python
+from flytekitplugins.kftensorflow import PS, Chief, CleanPodPolicy, RestartPolicy, RunPolicy, TfJob, Worker
+
+@task(
+    task_config=TfJob(
+        worker=Worker(
+            replicas=5,
+            requests=Resources(cpu="2", mem="2Gi"),
+            limits=Resources(cpu="2", mem="2Gi"),
+            restart_policy=RestartPolicy.FAILURE,
+        ),
+        ps=PS(replicas=1),
+        chief=Chief(replicas=1, restart_policy=RestartPolicy.ALWAYS),
+        run_policy=RunPolicy(clean_pod_policy=CleanPodPolicy.RUNNING),
+    ),
+    image="test_image",
+    resources=Resources(cpu="1", mem="1Gi"),

+1. Update flytepropeller to v1.6.0
+2. Update flytekit version to v1.6.1
 3. Update your code from:
     ```
     task_config=TfJob(num_workers=10, num_ps_replicas=1, num_chief_replicas=1),
