 This is the GitHub repository for contributing to the [Research Object](http://www.researchobject.org/) website.
 
 The `*.md` files use [MarkDown](https://guides.github.com/features/mastering-markdown) content that is rendered to <https://researchobject.github.io/> by [GitHub pages](https://pages.github.com/). Alias <http://researchobject.org/> will (eventually) map to the same URL space.
