 Some examples of the mechanisms and features that Volcano adds to Kubernetes are:
 
-1. Scheduling extensions, e.g:
+1. Job management extensions and improvements, e.g:
+    1. Multi-pod jobs
+    2. Lifecycle management extensions including suspend/resume and
+       restart.
+    3. Improved error handling
+    4. Indexed jobs

+2. Scheduling extensions, e.g:
     1. Co-scheduling
     2. Fair-share scheduling
     3. Queue scheduling
     4. Preemption and reclaims
     5. Reservartions and backfills
