New to the ereader world :)

Hello everyone, I am new to the ereader world..yes I am behind times..lol. I just purchased my first ereader a Kobo Vox. I was having trouble adding my files from the computer to the vox, so I went on you tube and found good ereader. They mentioned Calibre just starting using it I like it thus far. So my question is will any program updates be automatically downloaded, or do I have to search a link?
Thank you to those whom respond. :)
