Correct Virtual Host Setup

Hi, I am trying to setup Participad with SSL on top of my WP site. I installed etherpad-lite in a folder within public_html. I am trying to use a positive SSL certificate, however, the directions to setting up the virtual host (link below) are for subdomain setups (not subdirectory setups), and would require the more expensive wildcard SSL cert. https://github.com/ether/etherpad-lite/wiki/How-to-put-Etherpad-Lite-behind-a-reverse-Proxy#with-ssl-enabled What kind of setup does this require? Is this bit added below other <Virtual Host> sections, or within the same 443 port one? Or in a different .conf file altogheter, as a diferent server? Greatly appreciate your help with this.
