Every project on GitHub comes with a version-controlled wiki to give your
documentation the high level of care it deserves. It’s easy to create
well-maintained, Markdown or rich text documentation alongside your code.
yEd source files are in the yEd directory if this wiki is cloned (git clone https://github.com/duraspace/pcdm.wiki.git).
