Walking animation in Edge?

I am brand new to edge but am trying to create a stick figure animation for a web design class project.

I have done walking animations in Flash and that is the only program I've animated with.  I am wondering what process I should go through to make this animation in edge.

Would I just make it in flash and export it as a sprite sheet?

Any tips on what workflow I would use to get something like this done would be appreciated.

Thank you
