             Currently, the Yocto Project is supported on the following
             distributions:
+            <note>
+                Yocto Project releases are tested against the stable Linux
+                distributions in the following list.
+                The Yocto Project is not supported on "rolling releases" whose
+                frequent changes could break functionality.
+                Attempting to use the Yocto Project on any Linux distribution
+                that is not on the following list puts you into untested
+                territory.
+                Refer to
+                <ulink url='&OE_HOME_URL;/index.php?title=OEandYourDistro'>OE and Your Distro</ulink> and
+                <ulink url='&OE_HOME_URL;/index.php?title=Required_software'>Required Software</ulink>
+                for information for other distributions used with the
+                OpenEmbedded project, which might be a starting point for
+                exploration.
+                If you go down this path, you should expect problems.
+                When you do, please go to <ulink url='&YOCTO_BUGZILLA_URL;'>Yocto Project Bugzilla</ulink>
+                and submit a bug.
+                We are interested in hearing about your experience.
