Add Short Description Above

Hi,

I'm currently using the Classic template.

I want to add a short description about me on the home page above the posts. Something like this:

In my case, the top post is "Don't be lame" on my homepage abarkingcat.com. I want to add a short description above it.

Of course, if I continue to add content, the top post would be different. But I want the description about me to stay at the top.

How do I do it?
