LilyPond Contributor's Guide: 5. Documentation work

# 5. Documentation work

There are currently 11 manuals for LilyPond, not including the translations. Each book is available in HTML, PDF, and info. The documentation is written in a language called `texinfo` – this allows us to generate different output formats from a single set of source files.

To organize multiple authors working on the documentation, we use a Version Control System (VCS) called Git, previously discussed in Working with source code.
