This repo contains content in the html folder and an apache2 configuration that can be implemented with:
cd /var/www; git clone git@github.com:LAMurakami/gci
sudo ln -s /var/www/gci/gci_apache2.conf /etc/apache2/sites-available/000-gci.conf
sudo a2ensite 000-gci
sudo systemctl reload apache2
If the repo contents are installed in a location other than /var/www the path in the configuration and in the instuctions would have to be modified.
