+If you already configured git send-email, you can simply use `git-publish
+<https://github.com/stefanha/git-publish>`__ to send series.

+
+    $ git checkout master -b my-feature
+    $ # work on new commits, add your 'Signed-off-by' lines to each
+    $ git publish
+    $ ... more work, rebase on master, ...
+    $ git publish # will send a v2
+
+Each time you post a series, git-publish will create a local tag with the format
+``<branchname>-v<version>`` to record the patch series.
+
+When sending patch emails, 'git publish' will consult the output of
+'scripts/get_maintainers.pl' and automatically CC anyone listed as maintainers
+of the affected code. Generally you should accept the suggested CC list, but
+there may sometimes be scenarios where it is appropriate to cut it down (eg on
+certain large tree-wide cleanups), or augment it with other interested people.
