You'll need to download and install Stepmania, and then find and download a simfile pack from DDR.

Since DDR stepfiles are copywrited and you'd have to acquire pirated ones to play them on Stepmania, we aren't going to tell you around here where to get them.

what does it mean when you sightread something?

That you're playing it for the first time without ever having seen it before.
