This repo serves as the template/basis for our Quarto tutorials.
Repo templates come with a GitHub Action that will check that the CITATION.cff file is correctly formatted every time the file is pushed to GitHub (and it will check on any branch to which it is pushed.)
You can also run this check locally with the code below which 1) installs the cffconvert checker package, and runs the check (inside of a Docker container). You may need to install Docker and Python 3 if they are not already on your computer.
python3 -m pip install --user cffconvert
docker run --rm -v "${PWD}:/app" citationcff/cffconvert --validate
