-Acking diffs
-------------
+## Acking diffs
 
 This interface allows to ack differences in order to ease the report review. Differences are acked on all nodes that have the same resource with the same diff.
 
 A global acking button is available for sections which allows to ack all diffs in the section at once.
 
-Starring diffs
---------------
+## Starring diffs
 
 When using the global acking button, you might want to exclude some diffs from the global acking. Starring diffs does just that. Just as for acks, stars are cross-nodes.
