getting PMS to read MP3 files

I will be blunt I do not have ITunes I have a file of MP3’s a collection of my own music I would like to have them available on my Plex I have created my Libraries but al I get is this msg Libraries are currently being updated Hang tight while we look for your content and nothing is ever copies into the Library Ive read the previous posts and none make since to me please talk to me as if I were a 68 year old man because I am.

do you have a humongous amount of music?

Plex doesn’t copy anything. when you create a library you tell it what your main music folder is ( or multiple folders), such as C:\Music\iTunes\iTunes Media\Music then it scans for files and starts adding them to database and gathering metadata. The files stay where they are.

If you have a really huge amount of music this can take a while
