+The libraries are published to [kotlin-eap-1.1](https://bintray.com/kotlin/kotlin-eap-1.1/kotlinx.coroutines) bintray repository.
+
+These libraries require kotlin compiler version to be at least `1.1-M04` and 
+require kotlin runtime of the same version as a dependency, which can be obtained from the same repository.
