Well, it's not going to get less readable if you do nothing, which I think was the point. You're getting at being able to make it more readable with design, which is possible, and addressed a few sentences later. But, the defaults aren't too bad: black text on white, blue or purple hyperlinks with underlines, larger headings, responsive, etc. The one thing I would always do is enforce a maximum line length for larger monitors.
