repo: https://github.com/kynan/nbstripout
install in wsl:
sudo apt update
sudo apt install python3-pip
pip3 install --upgrade nbstripout
activate globally (i think prefered)
# when this command fails (because install /home/<user>/.local/bin in not in PATH)
nbstripout --install --global
# you can just use this as alternative:
python3 -m nbstripout --install --global
#than checkout your global .gitconfig
cd
cat .gitconfig
alternative, activate per repo:
# cd into root of repo
nbstripout --install
