so I've been around Kodi since it was known as XBMC and I have a Kodi windows machine but this is my first Pie experience so keep in mind my newness to the platform and hardware.
I loaded up LibreELEC onto my micro SD card and fired my Pie 4, 4GB b+ and was greeted by the set up instructions. I got my movie repo connected after some fussing but now I'd like to connect to the MySQL server that I have set up and I know I need to edit the advancesetting xml doc to do that but I can't seem to find where that doc is supposed to go in a non-windows machine. Everything I've found just points to the wiki which, to the best of my knowledge, doesn't say where this doc should go on a LibreELEC install.
Any help would be greatly appreciated!
