+@section Overview of compiling
+
+Compiling LilyPond from source is an involved process, and is only
+recommended for developers and packagers.  Typical program users
+are instead encouraged to obtain the program from a package
+manager (on Unix) or by downloading a precompiled binary
+configured for a specific operating system.  Pre-compiled binaries
+are available on the @rweb{Download} page.
+
+Compiling LilyPond from source is necessary if you want to build,
+install, or test your own version of the program.
+
+A successful compile can also be used to generate and install the
+documentation, incorporating any changes you may have made.
+However, a successful compile is not a requirement for generating
+the documentation.  The documentation can be built using a Git
+repository in conjunction with a locally installed copy of the
+program.  For more information, see @ref{Building documentation
+without compiling}.
+
+Attempts to compile LilyPond natively on Windows have been
+unsuccessful, though a workaround is available (see
+@rcontrib{LilyDev}).

+@subsection Requirements for compiling LilyPond
+
+This section contains instructions on how to quickly and easily get all
+the software packages required to build LilyPond.
+
+Most of the more popular Linux distributions only require a few simple
+commands to download all the software needed.  For others, there is an
+explicit list of all the individual packages (as well as where to get
+them from) for those that are not already included in your
+distributions' own repositories.
+
+@ignore
+I have tested all of the following four Linux Distributions listed here
+Using a simple virtual machine and the appropriate ISO image file
+downloaded from each distribution's own website.  The instructions
+documented were run immediately after the initial installation
+(without any further additional configuration to the OS) and I made sure
+that I was able to run the full set of make, make test-baseline, make
+check and a full make doc. - James

+The following instructions were tested on @q{Fedora} versions 22 & 23
+and will download all the software required to both compile LilyPond and
+build the documentation.
+
+@itemize
+
+@item
+Download and install all the LilyPond build-dependencies (approximately
+700MB);
+
+@example
+sudo dnf builddep lilypond --nogpgcheck
+@end example
+
+@item
+Download and install additional @q{build} tools required for compiling;
+
+@example
+sudo dnf install autoconf gcc-c++
+@end example
+
+@item
+Download @code{texi2html 1.82} directly from:
+@uref{http://download.savannah.gnu.org/releases/texi2html/texi2html-1.82.tar.gz};
+
+@code{texi2html} is only required if you intend to compile LilyPond's
+own documentation (e.g. to help with any document writing).  The version
+available in the Fedora repositories is too new and will not work.
+Extract the files into an appropriate location and then run the
+commands;
+
+@example
+./configure
+make
+sudo make install
+@end example
+
+This should install @code{texi2html 1.82} into @code{/usr/local/bin},
+which will normally take priority over @code{/usr/bin} where the
+later, pre-installed versions gets put.  Now verify that your operating
+system is able to see the correct version of @code{texi2html}.
+
+@example
+texi2html --version
+@end example
+
+@item
+Although not @q{required} to compile LilyPond, if you intend to
+contribute to LilyPond (codebase or help improve the documentation) then
+it is recommended that you also need to install @code{git}.

-To install GNU LilyPond, type
+@warning{make sure that you are in the @file{build/} subdirectory

+
+LilyPond is compiled with the @command{make} command.  Assuming
+@command{make} is configured properly, you can simply run:
 
 @example
-gunzip -c lilypond-x.y.z | tar xf -
-cd lilypond-x.y.z
-./configure		# run with --help for applicable options
 make
-su -c 'make install'
 @end example
 
-@noindent
-If you are not root, you should choose a @code{--prefix} argument that
-points into your home directory, e.g.
+@samp{make} is short for @samp{make all}.  To view a list of @command{make}
+targets, run:
 
 @example
-./configure --prefix=$HOME/usr
+make help
 @end example
 
-If you encounter any problems, please see @ref{Problems}.
+TODO: Describe what @command{make} actually does.
+
+@seealso
+@ref{Generating documentation} provides more info on the @command{make} targets
+used to build the LilyPond documentation.
+
+
+@node Saving time with the -j option
+@subsection Saving time with the @option{-j} option
+
+If your system has multiple CPUs, you can speed up compilation by
+adding @samp{-j@var{X}} to the @command{make} command, where
+@samp{@var{X}} is one more than the number of cores you have.  For
+example, a typical Core2Duo machine would use:
+
+@example
+make -j3
+@end example
 
+If you get errors using the @option{-j} option, and @samp{make}
+succeeds without it, try lowering the @code{@var{X}} value.
 
-@unnumberedsubsubsec Compiling for multiple platforms
+Because multiple jobs run in parallel when @option{-j} is used, it can
+be difficult to determine the source of an error when one occurs.  In
+that case, running @samp{make} without the @option{-j} is advised.
+
+@node Compiling for multiple platforms
+@subsection Compiling for multiple platforms
 
 If you want to build multiple versions of LilyPond with different
-configuration settings, you can use the @code{--enable-config=CONF}
-option of @command{configure}.  You should use @code{make conf=CONF}
-to generate the output in @file{out-CONF}.  For example, suppose you
-want to build with and without profiling, then use the following for

+build with and without profiling, then use the following for the
+normal build
 
 @example
 ./configure --prefix=$HOME/usr/ --enable-checking
 make
-make install
 @end example
 
 and for the profiling version, specify a different configuration
 
 @example

+If you configured @command{make} to install your local build in a

+
+The most time consuming task for building the documentation is
+running LilyPond to build images of music, and there cannot be
+several simultaneously running @command{lilypond-book} instances,
+so the @option{-j} @command{make} option does not significantly
+speed up the build process.  To help speed it up, the makefile
+variable @option{CPU_COUNT} may be set in @file{local.make} or on
+the command line to the number of @code{.ly} files that LilyPond
+should process simultaneously, e.g. on a bi-processor or dual core
+machine:
+
+@example
+make -j3 CPU_COUNT=3 doc
+@end example
+
+@noindent
+The recommended value of @option{CPU_COUNT} is one plus the number
+of cores or processors, but it is advisable to set it to a smaller
+value unless your system has enough RAM to run that many
+simultaneous LilyPond instances.  Also, values for the @option{-j}
+option that pose problems with @samp{make} are less likely to pose
+problems with @samp{make doc} (this applies to both @option{-j}
+and @option{CPU_COUNT}).  For example, with a quad-core processor,

+@unnumberedsubsec Using lilypond python libraries
 
 If you want to use lilypond's python libraries (either running
 certain build scripts manually, or using them in other programs),
 set @code{PYTHONPATH} to @file{python/out} in your build
-directory, or @file{.../usr/lib/lilypond/current/python} in the
+directory, or @file{@dots{}/usr/lib/lilypond/current/python} in the
 installation directory structure.

+@section Concurrent stable and development versions
+
+
+It can be useful to have both the stable and the development versions
+of Lilypond available at once.  One way to do this on GNU/Linux is to
+install the stable version using the precompiled binary, and run the
+development version from the source tree.  After running @command{make
+all} from the top directory of the Lilypond source files, there will
+be a binary called @code{lilypond} in the @code{out} directory:
+
+@example
+<@var{path to}>/lilypond/out/bin/lilypond
+@end example
+
+This binary can be run without actually doing the @code{make
+install} command.  The advantage to this is that you can have all
+of the latest changes available after pulling from git and running
+@code{make all}, without having to uninstall the old version and
+reinstall the new.
+
+So, to use the stable version, install it as usual and use the
+normal commands:
+
+@example
+lilypond foobar.ly
+@end example
+
+To use the development version, create a link to the binary in the
+source tree by saving the following line in a file somewhere in your
+@code{$PATH}:
+
+@example
+exec <@var{path to}>/lilypond/out/bin/lilypond "$@@"
+@end example
+
+Save it as @code{Lilypond} (with a capital L to distinguish it
+from the stable @code{lilypond}), and make it executable:
+
+@example
+chmod +x Lilypond
+@end example
+
+Then you can invoke the development version this way:
+
+@example
+Lilypond foobar.ly
+@end example
