Jupyter saves notebooks as ipynb files which contain data and metadata in the same file. This makes them hard to read/inspect outside of Jupyter. Sabela currently saves the entire notebook as a markdown file (without the outputs). In future, we should save multiple files that can be bundled together in a zip file - the markdown, the file metadata, and extra files that are packaged with the notebook.
