How do you export an animation (Rigged)

I just made my first rigged animation (Something very simple, just someone waving) and I was wondering how you could export the animation.

Hi, When you ask for help you need to provide more information like; Where are you trying to export it to?
What kind of rigging did you use?
Are there any constraints in your rig?
Are you trying to export the animation as AVI or image sequence?
You will get more response that way.
