+    Simapp takes initial configuration through helm chart. Above yaml files is initial config.
+    Operator can add multiple devices, device groups & slices in the initial config. If simapp
+    is already running then ``kubectl edit configmap simapp -n <namespace>`` can be used to update
+    the simapp configuration. Simapp handles config delete, modify & addition by watching configmap
+    for any changes. There is no need to restart simapp after configmap change. New config will
+    be automatically reloaded.
