writable

Let me preface my post by noting that I'm a new Unraid user. I got into the idea of running a home NAS with an older desktop, and Unraid has made it incredibly easy to get started. Well worth the cost. I was also really drawn into the idea of running a local emulation server through Emulatorjs. When setting up Emulatorjs, Unraid notified me that some of default Emulatorjs ports are used for other services/apps on my server. I learned how to see what ports are in use through a terminal command from a helpful post on this forum (lsof -Pni | grep LISTEN). I see that nginx is using port 80, which is set to be used by Emulatorjs by default. I didn't know what nginx is, so I googled it and learned that I really don't know what nginx is or does. I thought about changing Emulatorjs's default port from 80 to another one, but I'm not sure if that would cause more headaches later on-- and since I don't know what nginx is, I'm also not sure port 80 is meant to be shared between nginx and other services. Should I change the default Emualtorjs port? Or should I go about solving this issue another way? Thanks in advance for any suggestions!
