I'm trying to follow the php course on ubuntu linux. I was able to get apache and mysql working, where I can query them with systemctl and sevice commands to check status and restart and stop/start. I see the apache splash page on localhost. What I don't quite understand is the default files are kept in /var/www/index.html. I am not able to modify these files from vscode or atom. Is there a good way to change the location where the projects will be located. I don't really like windows at all, and I don't have a mac, so the mamp server shown in the training is not available to me.
