 TEST POD
 ========
 
+Description
+-----------
+Testpod is developer tool to simulate 5G NFs and control NF behaviour as
+per test case requirement. Currently, it simulates AMF, NRF, PCF, UDM and UPF.
+While all other NFs run virtually on single pod, SMF runs on actual image on another pod.
+
+The Testpod can be run locally on any environment having miniKube via helm test package
+file present in repository OR locally as in binary mode.
+
