You can use various developers or mixtures of developers. I used to do it with HC-110 in various dilutions (usually anywhere from 1:63 to 1: 127), and it worked well, but I now prefer Dave Soemarko's LC-1 formula, which I found out about from the Christopher James Alt. Processes book. You vary mixtures to control the contrast. Remember that is is an ortho film, so it won't pick up warm light very well. One great thing (besides the fact that it is so cheap) is that you can somewhat develop it by inspection under a normal red safelight. (I develop in the dark unless making a brief inspection, however.) It does tend to get pinholes in my experience, so I would practice your film touch up skills!
