Read the readme - that´s what it was made for :)
Simply unzip the entire contents of the zip file into your content folder.
Then select one of the backgrounds in the folder "Light Presets - SmidA - Fake HDRI". Additionally I packed some presets for the domerotation in 45°-steps. This works with any HDRI you use. For best results in the render, turn off the headlamp of your camera. The fine tuning of the rotation you take at the end in the renderettings. Switch the aux preview to the Iray-preview.
Why do I call this "Fake HDRI"? I don't have any software with which I can create "real" HDRIs. So I created the underlying images with PSE, saved them as jpg and then changed them with an online tool (jpg to hdr). That means, it doesn't have the full dynamics of a real HDRI, but it works...
It would be nice if you mentioned me when using it - the best would be to send me a link to your picture: https://www.deviantart.com/smida460
