Wiring light from 2 on/off switches

I want to install a light middway between the first and second floor above the stairs. I would like to be able to turn light on/off from both 1st and 2nd floors. Is this possible, and can anyone give me directions?
Thanks

The wiring is easy once we get some of the basics out of the way. But getting the wiring inside the walls might not be so easy. Are the walls open? Or do you plan to rip down some drywall? What did you have in mind for a power source? And where might that power source be? Have you ever done any electrical work? Do you own any home wiring books?

If you don't have any home wiring books yet, I suggest you start by getting and reading one. The Black and Decker Complete Guide to Home Wiring is a good first book.

Thanks for the response. I've done most of the wiring in my house, including new circut breaker from the old bus fuses. The walls are open right now and I will be running new wire from breaker box. I've just never run into this before, and the Black and Decker book leaves me confused, I must be having a brain fart as my daughter says. Any suggestions word be appreciated.

This is standard 3-way switch wiring. There are five main ways to do this. I'll use "-" to indicate 14/2 cable, and "=" to indicate 14/3 cable:
1. Power-S1=S2-L.
2. Power-S1=L=S2.
3. Power-S1-L and S1=S2.
4. Power-L=S1 and L=S2.
5. Power-L-S1=S2.
People often have a preference for one or the other based on the topology of their home and where the panel is. If you have no preference, I suggest you use the first approach, as it is the most idiot proof. There are many web sites which show you the connections. Here's a site that shows you how to wire all five options.
