+  categoryDescription: |
+    Pod-CPU-Hog contains chaos to consume CPU resouces of specified containers in Kubernetes pods.  
+    - Causes high CPU resource consumption utilizing one or more cores by triggering md5sum commands
+    - The application pod should be healthy once chaos is stopped. Expectation is that service-requests should be served despite chaos.
