The default logo (normally located at the top left o fthe page) is actually quite easy to change.
The first thing you will need of-course is a logo. The dimensions are not important but we would recommend that a short logo would be better than a tall one as it leaves more space ofr the menu, banner and content to appear.
Once you have your logo you can upload it through the medie manager or even import it directly when changing the logo by selecting the "Browse" and "Start Upload" options when you select your logo.
The short video below shows you how to get this done in a few simple steps.
