NaNo Update

So, today, my blag entry is supposed to be NaNo update, but I have no idea what that means. Do I put up part of my novel? Do I write about how cool my novel is, or how much better I have gotten at writing? Or how much fun I have doing crazy people? Or how I am mixing mystery elements into my regular story, and assume that people are enough on top of it to figure out what I mean? I don't know.
