+# Topics
+
+Creating a New Topic
+```
+kafka-topics --create --zookeeper localhost:2181 --replication-factor 1 --partitions 3 --topic my-topic
+```
+Verify the topic
+```
+kafka-topics --list --zookeeper localhost:2181
+```
+Adding Partitions
+```
+kafka-topics --zookeeper localhost:2181 --alter --topic my-topic --partitions 16
+```
+Deleting a Topic
+```
+kafka-topics --zookeeper localhost:2181 --delete --topic my-topic
+```
+Listing All Topics in a Cluster
+```
+kafka-topics --zookeeper localhost:2181 --list
+```
+Describing Topic Details
+```
+kafka-topics --zookeeper localhost:2181/kafka-cluster --describe
+```
+Show Under-replicated Partitions for topics
+```
+kafka-topics --zookeeper localhost:2181/kafka-cluster --describe --under-replicated-partitions
+```
+
+# Producers
+Produce messages standard input
+```
+kafka-console-producer --broker-list localhost:9092 --topic my-topic
+```

+```
+And enter a few values from the console:
+```
+{"f1": "value1"}
+```
+
+# Consumers
+
+## Consume messages
+
+Start a consumer from the beginning of the log
+```
+kafka-console-consumer --bootstrap-server localhost:9092 --topic my-topic --from-beginning
+```
+Consume 1 message
+```
+kafka-console-consumer --bootstrap-server localhost:9092 --topic my-topic  --max-messages 1
+```
+
+Consume 1 message from `__consumer_offsets`
+```
+kafka-console-consumer --bootstrap-server localhost:9092 --topic __consumer_offsets --formatter 'kafka.coordinator.GroupMetadataManager$OffsetsMessageFormatter' --max-messages 1
+```
+
+Consume, specify consumer group:
+```
+kafka-console-consumer --topic my-topic --new-consumer --bootstrap-server localhost:9092 --consumer-property group.id=my-group
+```
+
+## Consume Avro messages
+```
+kafka-avro-console-consumer --topic position-reports --new-consumer --bootstrap-server localhost:9092 --from-beginning --property schema.registry.url=localhost:8081 --max-messages 10
+```
+
+```
