+<p>Keep in mind that an issue tracker is not a user support forum. It is a list
+of pending technical tasks, along with information relevant for those tasks,
+and information about progress on those tasks including which ones might
+get worked on in the short term.</p>
+<p>This issue tracker is narrowly focused on the Android Open Source Project.
+Issues with retail devices need to be reported through those devices' support
+channels, especially for devices other than Nexus. Issues with applications
+that aren't part of AOSP need to be reported with those applications'
+developers; that is also the case for Google applications.</p>
 <p>Please note that we can't guarantee that any particular bug can be fixed in
 any particular release. To see what happens to your bug once you report it,
