 There are multiple ways to use `jupytext`:
 - Directly from Jupyter Notebook or JupyterLab. Jupytext provides a _contents manager_ that allows Jupyter to save your notebook to your favorite format (`.py`, `.R`, `.jl`, `.md`, `.Rmd`...) in addition to (or in place of) the traditional `.ipynb` file. The text representation can be edited in your favorite editor. When you're done, refresh the notebook in Jupyter: inputs cells are loaded from the text file, while output cells are reloaded from the `.ipynb` file if present. Refreshing preserves kernel variables, so you can resume your work in the notebook and run the modified cells without having to rerun the notebook in full.

 - Code cells are exported verbatim (except for Jupyter magics, which are commented), and separated with blank lines. Code cells are reconstructed from consistent Python paragraphs (no function, class or multiline comment will be broken).
 - Cells that contain more than one Python paragraphs need an explicit start-of-cell delimiter `# +` (`// +` in C++, etc). Cells that have explicit metadata have a cell header `# + {JSON}` where the metadata is represented, in JSON format. The end of cell delimiter is `# -`, and is omitted when followed by another explicit start of cell marker.

 A variation of the `light` format is the `bare` format, with no cell marker at all. Please note that this format will split your code cells on code paragraphs. By default, this format still includes a YAML header - if you prefer to also remove the header, set `"notebook_metadata_filter": "-all"` in the jupytext section of your notebook metadata.

 Percent scripts created by Jupytext have a header with an explicit format information. The format of scripts with no header is inferred automatically: scripts with at least one `# %%` cell are identified as `percent` scripts. Scripts with at least one double percent cell, and an uncommented Jupyter magic command, are identified as `hydrogen` scripts.
