Man, do I love learning new things. Was knocking out some training today, and this presenter Stephen Grider was using draw.io. Not to big of a deal, I have used many online/offline diagramming solutions before. How Stephen was using it though, I have never thought of leveraging Github as the destination to store drawings. Stephen had all the course drawings on a public repo that you can point draw.io to import from. So then I was wondering, can draw.io save to a repo, and it does with ease in an XML compressed format.
This is just another clever way to leverage GitHub and store any type of diagrams you may have related to your projects.
