About the documentation

OpenFISMA documentation is version controlled just like the source code. The documentation is written in MultiMarkdown format, which is a line-oriented, text-based format that is easy to read even in its raw format. You can view the version history for the documentation on our version control site.

Any time a project member updates a piece of documentation, our continuous integration server converts the documentation to multiple formats (such as HTML and PDF) and publishes it on this website. This keeps the documentation fresh and makes it more useful for everybody: business analysts, evaluators, project managers, and developers.
