 `kafka-streams-scala` is published and cross-built for Scala `2.11`, and `2.12`, so you can just add the following to your build:
 
 ```scala
-val kafka_streams_scala_version = "0.1.2"
+val kafka_streams_scala_version = "0.2.0"
 
 libraryDependencies ++= Seq("com.lightbend" %%
 "kafka-streams-scala" % kafka_streams_scala_version)
 ```
 
 > Note: `kafka-streams-scala` supports onwards Kafka Streams `1.0.0`.
 
-The API docs for `kafka-streams-scala` is available [here](https://developer.lightbend.com/docs/api/kafka-streams-scala/0.1.2/com/lightbend/kafka/scala/streams) for Scala 2.12 and [here](https://developer.lightbend.com/docs/api/kafka-streams-scala_2.11/0.1.2/#package) for Scala 2.11.

 ## Running the Tests
 
 The library comes with an embedded Kafka server. To run the tests, simply run `sbt testOnly` and all tests will run on the local embedded server.
 
-> The embedded server is started and stopped for every test and takes quite a bit of resources. Hence it's recommended that you allocate more heap space to `sbt` when running the tests. e.g. `sbt -mem 1500`.
