Well, the about page doesn't have to be a cheesy "We have made the perfect library" kind off page. You can just tell what kind of library it is, What it's goals are (Simplicity, Performance, 3D or 2D, Certain features or whatever), How long it has been around and what games are made with it (history). Also mention that it's opensource, because I missed that.

Good to know that it's opensource. I'll have a closer look at it soon.
