Editing Documentation (section)

=== Software Documentation Folder (SDF) tool ===
A '''common type''' of software document written in the simulation industry is the SDF. When developing software for a simulator, which can range from embedded avionics devices to 3D terrain databases by way of full motion control systems, the engineer keeps a notebook detailing the development "the build" of the project or module. The document can be a wiki page, Microsoft Word document or other environment.  They should contain a ''requirements'' section, an ''interface'' section to detail the communication interface of the software.  Often a ''notes'' section is used to detail the proof of concept, and then track errors and enhancements. Finally, a ''testing'' section to document how the software was tested.  This documents conformance to the client's requirements. The result is a detailed description of how the software is designed, how to build and install the software on the target device, and any known defects and workarounds. This build document enables future developers and maintainers to come up to speed on the software in a timely manner, and also provides a roadmap to modifying code or searching for bugs.
