After publishing, a good minimal sanity check is to ensure that you can render the template as mentioned in play with the template:
cd ~
# Get rid of the global npm link development version just to make sure it is not being used.
npm uninstall -g ourbigbook
git clone https://github.com/ourbigbook/template
cd template
npm install
npx ourbigbook .
firefox _out/html/index.html
