+Defender for Endpoint on Linux can be deployed from one of the following channels (denoted as [channel]): 
+
+- `insiders-fast`
+- `insiders-slow`
+- `prod` 
+
+Each of these channels corresponds to a Linux software repository. The instructions in this article describe configuring your device to use one of these repositories. 
+
+The choice of the channel determines the type and frequency of updates that are offered to your device. Devices in insiders-fast are the first ones to receive updates and new features, followed later by insiders-slow and lastly by prod. 
+
+In order to preview new features and provide early feedback, it's recommended that you configure some devices in your enterprise to use either `insiders-fast` or `insiders-slow`.
