It processes like any other B&W film. datasheets with processing recommendations are on Ilford's website.
It's considered a "near infrared" film rather than a true infrared like the late Kodak HIE. What that means is that it's sensitivity doesn't go as far into the infrared realm as Kodak HIE did, or the Rollei infrared.
But, with the right filtration it will give you some of the infrared look like light foliage and black skys
It's a little grainy compared to FP4 or even HP5, but it has a nice look. I've had better luck with it as a general purpose film than infrared, but YMMV.
Unlike "true" infrared films, you can load it into the camera in normal or subdued light rather than in a darkroom, which was Kodak's recommendation for HIE, and I believe, is recommended for the Rollei product.
