One of the benefits of using DocGen for product software documentation is that its plain text source files are easy to version control using any modern version control tool such as git.
It is recommended to store the documentation source files (DocGen input directory) in the same version control repository as its parent project. For example, if you are using DocGen to document a software product, each release of the software app can then have a matching documentation version.
It is not necessary to version control the DocGen output, because this can always be regenerated.
