+## Usage
+This module contains example topologies demonstrating storm-kafka-client
spout and Trident usage.
+
+The module is built by `mvn clean package`. This will generate the
`target/storm-kafka-client-examples-VERSION.jar` file. The jar contains all
dependencies and can be submitted to Storm via the Storm CLI. For example:
+```
+storm jar storm-kafka-client-examples-2.0.0-SNAPSHOT.jar
org.apache.storm.kafka.spout.test.KafkaSpoutTopologyMainNamedTopics
+```
+will submit the topologies set up by KafkaSpoutTopologyMainNamedTopics to
Storm.
+
+Note that this example produces a jar containing all dependencies for ease
of use. In a production environment you may want to reduce the jar size by
extracting some dependencies (e.g. org.apache.kafka:kafka-clients) from the
jar. You can do this by setting the dependencies you don't want to include in
the jars to `provided` scope, and then manually copying the dependencies to
your Storm extlib directory.

Thanks, I didn't know about this flag. It's much better, will replace
references to extlib.
