 # spring-boot-kafka
 
-This module contains articles about Spring with Kafka
-
 Intro
 This is a simple Spring Boot app to demonstrate sending and receiving of messages in Kafka using spring-kafka.
 
 As Kafka topics are not created automatically by default, this application requires that you create the following topics manually.
 
-``
+```
 $ kafka-topics --create --zookeeper localhost:2181 --replication-factor 1 --partitions 1 --topic kafkaexample
 $ kafka-topics --create --zookeeper localhost:2181 --replication-factor 1 --partitions 5 --topic portitioned
 $ kafka-topics --create --zookeeper localhost:2181 --replication-factor 1 --partitions 1 --topic filtered
 $ kafka-topics --create --zookeeper localhost:2181 --replication-factor 1 --partitions 1 --topic greeting
-``
+```
 
 When the application runs successfully, following output is logged on to console (along with spring logs):
 
 Message received from the 'kafkaexample' topic by the basic listeners with groups test and sample
-``
+
+```
 Received Message in group 'test': Hello, World!
 Received Message in group 'sample': Hello, World!
-``
+```
 
 Message received from the 'kafkaexample' topic, with the partition info
-``
+
+```
 Received Message: Hello, World! from partition: 0
-``
+```
 
 Message received from the 'partitioned' topic, only from specific partitions
-``
+
+```
 Received Message: Hello To Partioned Topic! from partition: 0
 Received Message: Hello To Partioned Topic! from partition: 3
-``
+```
 
 Message received from the 'filtered' topic after filtering
-``
+
+```
 Received Message in filtered listener: Hello Rajesh!
-``
+```
 
 Message (Serialized Java Object) received from the 'greeting' topic
-``
+
+```
 Received greeting message: Greetings, World!!
-``
+```
