+@section LilyDev
+
+There is a disk image of a @q{remix} of Debian GNU/Linux available for
+download which includes all the necessary software and tools to compile
+both LilyPond and the documentation. Called the
+@qq{Debian LilyPond Developer Remix}, but known simply as @qq{LilyDev}
+for short. Although it is not possible to compile LilyPond on Windows
+and extremely difficult on MacOS, LilyDev can be installed and run
+inside a @q{virtual machine} on any of these operating systems without
+disturbing your main operating system. The LilyDev disk image can also
+be burnt to a DVD or copied to a USB stick and installed like any
+other GNU/Linux distribution.
+
+Most virtualization software can be used but we recommend VirtualBox as
+it is available for all major operating systems and is easy to install
+& configure.
+
+If you are not familiar with GNU/Linux, it may be beneficial to read a
+couple of @qq{introduction to Linux} web pages.
+
+For those interested, the LilyDev remix is currently based on a 32bit
+version of Debian 7 (Wheezy). The image is generated using Debian
+@uref{http://live.debian.net/, live-build} and the configuration
+files are hosted on GitHub:
+
+@smallexample
+@uref{https://github.com/fedelibre/LilyDev}

+@warning{Apart from installing and configuring LilyDev in VirtualBox,
+the rest of the chapter assumes that you are comfortable using the
+command-line. While this chapter is intended for users who may have
+never created a patch or compiled software before, experienced
+developers (who prefer to use their own development environment) may
+still find it instructive to skim over this section.}
