I have had great difficult navigating this theme, as much as I love the look of it. I am a new blog builder and haven't been able to easily discover what features are called, how to edit and customize them, and how they work. 

In the Craft and DIY template for this theme, on the homepage, just below the header, there are 3 boxes which appear to me to be another menu. I do not know what they are called and I cannot, for the life of me, seem to find where to edit them so that I can change the images, links, and titles of these boxes. They're darling, but after combing through my options several times, I am still at a loss. 

I have attached a screen shot of them.
