First, please forgive me if I have posted this in an incorrect section, my only excuse is that I'm new here and feel as though I am blundering around much like the proverbial bull in a china shop, only with a lot less finesse.
I have completed my first 1 minute recording, (It's actually only about 45 seconds long), and I had spent several hours trying to work out where to upload it to, when I came across a link in this document, (https://wiki.librivox.org/index.php/User:Philchenevert), pointing me to a YouTube Video, (How to upload your 1 minute test - https://www.youtube.com/watch?v=J83ZLPb4Xu8). Unfortunately this video is private and therefore I am unable to view it. I couldn't even find anywhere to enter a user name & password

Can someone please, in words of one syllable, explain where to upload the MP3 file.
I think I am relatively comfortable on the process of uploading my file, my problem is the location where to upload it to.
Thank you
