At Authorea, we want to change the way scientists communicate and share their research. This includes giving all the information behind figures a place to live: by letting readers and reviewers access your data and code, your results can be easily reproduced and extended.  It's really easy to incorporate IPython Notebooks as well as  in your articles. First, upload a figure to your article. You can do so by dragging and dropping an image or by clicking \textbf{Insert Figure} at the bottom of the block you want it under. When your figure is in place you can \textbf{attach data} to it. We take json, csv, dat files and \textbf{IPython Notebooks}.
