Summary

• document how to protect branches, manage permissions and invite collaborators on GitHub
• allow converting README.ipynb without nbconvert by falling back to a simple JSON-based exporter

Testing

• python filter_nb_metadata.py < README.ipynb > README_clean.ipynb && mv README_clean.ipynb README.ipynb
• python convert_ipynb_to_md_and_py.py README.ipynb
• pip install nbconvert (fails: Could not find a version that satisfies the requirement nbconvert)
