 ## Kotlin Extensions for RxJava
 
 RxKotlin is a lightweight library that adds convenient extension functions to [RxJava](https://github.com/ReactiveX/RxJava). You can use RxJava with Kotlin out-of-the-box, but Kotlin has language features (such as [extension functions](https://kotlinlang.org/docs/reference/extensions.html)) that can streamline usage of RxJava even more. RxKotlin aims to conservatively collect these conveniences in one centralized library, and standardize conventions for using RxJava with Kotlin.

 The maintainers do not update the RxJava dependency version for every RxJava release, so you should explicitly add the desired RxJava dependency version to your `pom.xml` or `build.gradle(.kts)`.

 ## SAM Helpers
 
-To help cope with the [SAM ambiguity issue](https://youtrack.jetbrains.com/issue/KT-14984) when using RxJava 2.x with Kotlin, there are a number of helper factories and extension functions to workaround the affected operators.
