Reattaching aluminum siding?

[Jey]

Do you staple each panel of the aluminum siding at the top and the bottom or just the bottom? I thought when I looked at mine it had holes where staples may have been before on the top of the seems that tuck under the piece above it but the videos I just watched show them stapling just the bottoms?

I imagine there are different types of siding.  I've only seen it done like the attached video, hooks on the top, staple on the bottom.

Man they make that look easy. I sure hope it?s just the bottom so I don?t have to unhook more pieces
