where do you upload your ePub? need help, please...

Hi,

I am new to these forums and I have had a designer create an ePub for me.

I don't particularly want to use an aggregator - but I would like to know where the

area and the guidelines and diretions are to upload the ePub, after my application

is approved. I was able to submit my application today, though iTunes connect - but

I didn't see anything else there that I could do (which is why I assume that the

area to upload books is somewhere else, etc.).

Can anyone point me in the right direction, please. It would be highlighy appreciated.

Thanks.😕
