I have not watched it. The link to all the Kobo user guides can be found at: http://www.kobo.com/userguides
I'm not a huge fan of using the store, so I just don't click on the buttons that take me there.
Further to what Taming said, the key thing with adding fonts is that you have to be very careful with naming -- the directory name is case sensitive and to get bold/italics etc to work they need to be named properly. Do a search on add fonts and there are a number of threads with detailed directions. I know it works because I double checked and my sideloaded Roboto font is still working on my KT and works on my KG.
You will have to find a Delima font to add.
