+### _As described in the illustration above, here is how the indexer works:_
 
-* Kafka has a topic named, say `Topic_1`
+* Kafka has a topic named, say `Topic1`
 
-* Lets say, `Topic_1` has 5 partitions.
+* Lets say, `Topic1` has 5 partitions.
 
 * In the configuration file, kafka-es-indexer.properties, set firstPartition=0 and lastPartition=4 properties 
 
-* start the standalone indexer application as described below 
+* start the indexer application as described below 
 
 * there will be 5 threads started, one for each consumer from each of the partitions
