+@node Producing a patch
+@subsection Producing a patch
+
+Once you have finished editing your files, checked that your changes
+meet the @ref{Code style}, and/or @ref{Documentation policy}, properly
+set up your name and email in @ref{Git user configuration}, and
+checked that the entire thing compiles, you may:
+
+@example
+git commit -a
+git format-patch origin
+@end example
+
+The commit should include a brief message describing the change.
+This consists of a one-line summary describing the change, and
+if necessary a blank line followed by several lines giving the
+details:
+
+@example
+Did household chores.
+
+I hung up the wet laundry and then washed the car. I also
+vacuumed the floors, rinsed the dirty dishes, fed the cat, and
+recalibrated the temporal flux machine.
+@end example
+
+If the change is to the documentation only then the one-line
+summary should be prefixed with @qq{Docs: }.
+
+If you added a file to the source code, you must add it to git
+with:
+
+@example
+git add FILENAME
+@end example
+
+@noindent
+(and possibly modify the @file{GNUmakefile})
+
+These commands will produce one or more files named
+@file{0001-xyz}, @file{0002-abc}, etc. in the top directory of the
+git tree. Send an email to @email{lilypond-devel@@gnu.org} with
+these files attached, and a developer will review and apply the
+patches to the main repository.
+
+
+@node Committing directly
+@subsection Committing directly
+
+Most contributors do not have permission to commit directly. If you
+do, make sure you have set up your name and email in @ref{Git user
+configuration}, then edit @file{.git/config}: change the line
+
+@example
+url = git://git.sv.gnu.org/lilypond.git/
+@end example
+
+@noindent
+into
+
+@example
+url = ssh://@var{user}@@git.sv.gnu.org/srv/git/lilypond.git
+@end example
+
+@noindent
+where @var{user} is your login name on Savannah.
+
+If you have not already done so, you should generate and upload a
+SSH key: open @uref{https://savannah.gnu.org/my/} in your browser,
+go to @q{Account Configuration}, then to something like
+@q{Edit SSH Keys}, and follow the instructions on that page.
+
+You may then:
+
+@example
+git push origin
+@end example
+
+Note that recent versions of Git (Git 1.6.3 or later) will issue a
+big warning if the above command is used. The simplest solution
+is to add a new section to @file{.git/config} that looks like
+this:
+
+@example
+[push]
+ default = matching
+@end example
+
+@noindent
+Then @code{git push origin} will work as before. For more
+details, consult the @code{git push} man page.

+@warning{This section is not necessary for normal contributors;
+these commands are presented for information for people interested
+in learning more about git.}
+
+
+It is possible to work with several branches on the same local Git
+repository; this is especially useful for translators who may have to
+deal with both @code{lilypond/translation} and a stable branch,
+e.g. @code{stable/2.12}.
+
+Some Git commands are introduced first, then a workflow with several
+Git branches of LilyPond source code is presented.
