Idk, its pretty simple, in the install it pretty much does everything for you, then go into settings, make a few changes (password etc) then i use no-ip.com to make a dynamic ip address. I type that into iPhone and viola, i view my PC from my iPhone.
(there is a lot more to it than that, just google it and a lot of stuff comes up on it. YouTube will help a lot.)
If any1 needs further help on this, message me and I would be glad too.
(Maybe make a Guide on this?)
