How to install HP prime program in HP Prime iOS

[mark4flies]

I realize that installing a HPPL program is pretty basic but I am confused. I understand that all I need to do is to drag a file in the Connectivity Kit to the connected Prime, but which file? The Zip files from HPCalc.org often contain many files. Which ones are needed on the calculator? Maybe a related question is what are all these files for?

Thanks so much!
