Levels for ZDoom

I hate to be the newbie that asks this, but how do I load external wads in ZDoom?

That should be all you need.

thanks a lot. hopefully i will release my very first level (or at least the first i deem of enough quality to release) very soon, but i wanted to try it with zdoom first, 'cause i doubt anyone will play it with doom95 or something.
