Depending on the humidity in your area, you'll either want to humidify it (providing you live in a lower humidity area), or control the humidity (if you live in a rainforest, haha).
I suggest purchasing an in-guitar humidifier, similar to this:

The humidistat is a nice addition, but not very necessary as they are often notoriously inaccuate. Unless you pick up an expensive one, expect it to be off.
You'll want to ensure you keep that puppy of yours humidified properly, because during manufacturing process, it's kept a specific humidity as well. If you neglect to do so, your guitar will suffer some pretty interesting consequences ranging from simply dryness, all the way to finish cracking, and even cracking of the fretboard (extreme case).
I purchased the planet waves humidifier for about $15.00 CAN without the humidistat, and it works like a charm. Fill it once every couple weeks, and it does the job perfectly.
I wouldn't suggest getting a damp-it guitar humidifier unless is ISN'T the one that looks like a long sponge...
There are many humidity resources on the internet, but my favourite come from Jean Larrivee.
Good luck.
