To complete or present in another form the introduction to Git usage
in this chapter, it may be a good idea to look for Git documentation

For more info, see @uref{http://lilypond.org/gub}. The git
location is:

@example
-git pull origin
+git pull -r
@end example
checked that the entire thing compiles, you may:
@example
-git commit -a
+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:
@noindent
(and possibly modify the @file{GNUmakefile})
-Send an email to @email{lilypond-devel@@gnu.org} with the diff as
-an attachment.
+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.

You may then:
git push origin

+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

+@node Reverting all local changes
+@subsection Reverting all local changes
+
+Sometimes git will become hopelessly confused, and you just want
+to get back to a known, stable state. This command destroys any
+local changes you have made, but at least you get back to the
+current online version:
+
+@example
+git reset --hard origin/master

+which is not a full git installation) and
+install it.
+
+Note that most users will not need to install SSH. That is not
+required until you have been granted direct push permissions to
+the master git repository.
Start Git by clicking on the desktop icon.
This will bring up a command line bash shell. This may be
call the folder to contain the repository [path]/Git.
You will need to have space for around 150Mbytes.
-In the git bash shell type
+Start the Git bash shell by clicking on the desk-top icon installed
+with Git and type

cd [path]/Git
left-hand (Git Repository) panel. Leave everything
else unchanged and save it.
+Note that Windows users must leave the default setting for line
+endings unchanged. All files in a git repository must have lines
+terminated by just a LF, as this is required for Merge to work, but
+Windows files are terminated by CRLF by default. The git default
+setting causes the line endings of files in a Windows git repository
+to be flipped automatically between LF and CRLF as required. This
+enables files to be edited by any Windows editor without causing
+problems in the git repository.
+
@subsection Checking out a branch
At this stage you have two branches in your local repository,
Once familiarity with using git on Windows has been gained the
standard git manuals can be used to learn about these.
