 Here are some examples of such a note:
 </p>
 <ul>
-  <li>NOTE: This is a candidate for the 9.0 branch.</li>
-  <li>NOTE: This is a candidate for the 8.0 and 9.0 branches.</li>
-  <li>NOTE: This is a candidate for the stable branches.</li>
+  <li>CC: &lt;mesa-stable@lists.freedesktop.org&gt;</li>
+  <li>CC: "9.2 10.0" &lt;mesa-stable@lists.freedesktop.org&gt;</li>
+  <li>CC: "10.0" &lt;mesa-stable@lists.freedesktop.org&gt;</li>
 </ul>
 
+Simply adding the CC to the mesa-stable list address is adequate to nominate
+the commit for the most-recently-created stable branch. It is only necessary
+to specify a specific branch name, (such as "9.2 10.0" or "10.0" in the
+examples above), if you want to nominate the commit for an older stable
+branch. And, as in these examples, you can nominate the commit for the older
+branch in addition to the more recent branch, or nominate the commit
+exclusively for the older branch.
+
+This "CC" syntax for patch nomination will cause patches to automatically be
+copied to the mesa-stable@ mailing list when you use "git send-email" to send
+patches to the mesa-dev@ mailing list. Also, if you realize that a commit
+should be nominate for the stable branch after it has already been commited,
+you can send a note directly to the mesa-stable@lists.freedesktop.org where
+the Mesa stable-branch maintainers will receive it. Be sure to mention the
+commit ID of the commit of interest (as it appears in the mesa master branch).
