No Tutorials for HDR

On the Mac App store this looks like its super easy to use. I have bought in the past the HDR Darkroom, and now Great Photo, none of these are nearly close to simplicity of editing the HDR photo at all. I would keep this software if only there was some kind of help/tutorial online that would enable me to learn it.
Otherwise I would not recommend this to anyone.
