+## Preview Build
+For Android Nougat users, or users with bugs, there may be preview builds available from the [AdAway XDA Thread](http://forum.xda-developers.com/showthread.php?t=2190753). It is recommended to try those builds to see if your issue is resolved before creating an issue. The preview builds may contain bug fixes or new features for new android versions.  You can also obtain Preview or Stable builds from the [XDA Labs](https://labs.xda-developers.com/store/app/org.adaway) application.
+
+## Stable Build
+After preview builds have been tested a bit by the more technical or responsive community within the forums, we will then post the stable build to F-Droid.
