Let me start over and try again
How do I move the files from "public" to the folder I want....in laymens terms how do I do this part: Simply move all the files inside the public directory (including .htaccess) into the directory you want to serve Flarum from. Then edit .htaccess and uncomment lines 9-15 in order to protect sensitive resources. For Nginx, uncomment lines 8-11 of .nginx.conf.
I don't understand what it means by uncomment.
