 ### Enable RedshiftSink Exporter (optional)
 By default the exporter is disabled. This feature will work only when the Prometheus is also enabled.
 
-#### Why export Redshift metrics to Prometheus?
+#### Why to export Redshift metrics to Prometheus?
 We throttle the loads to keep the READ fast. Throttling logic by default treats all tables as same. But if the redshift exporter is enabled the less frequently used tables are throttled and not all tables are treated as the same. This is helpful in reducing the load in Redshift and keeping the queries fast.
 
 #### How to enable?
 - Prerequisite: Enable Throttling. Please see above.
 - Install the table scan view.
