So i'm brand new to this and dying to try out some add-ons on my forum. Problem is i'm clueless on how to actulally install them. The second I see - Upload contents of upload folder to forum root. or Upload the contents of the upload folder to the library folder of your XenForo installation. I panic and give in mostly because i have no idea what or where my forum root and library folders are. Can someone point me to where I can find these in simple terms.
