+# Kotlin Adaptor for RxJava
+
+This adaptor allows Kotlin Functions to be used and RxJava will know how to invoke them
+
+This enable code such as:
+
+```kotlin
+Observable.toObservable("one", "two", "three")
+    .take(2)
+    .subscribe{ (arg:String) ->
+        println(arg)
+    }
+```
+
+In the future this module will expose a more idiomatic way to use RxJava inside Kotlin
+
+# Binaries
+
+Binaries and dependency information for Maven, Ivy, Gradle and others can be found at [http://search.maven.org](http://search.maven.org/#search%7Cga%7C1%7Ca%3A%22rxjava-kotlin%22).
+
+Example for Maven:
+
+```xml
+<dependency>
+    <groupId>com.netflix.rxjava</groupId>
+    <artifactId>rxjava-kotlin</artifactId>
+    <version>x.y.z</version>
+</dependency>
+```
+
+and for Ivy:
+
+```xml
+<dependency org="com.netflix.rxjava" name="rxjava-kotlin" rev="x.y.z" />
