(Sorry for my bad english!)

Hi everybody, i have some question about "Photon server" for my Android Game
I don't understand how it's work after read all the documentation ..

I want to use Photon server for a MMORPG but i don't know how begin with photon server ..
I have to Host it on a rent server ? I don't want to use my computer to host it, i want my server "safe" away my connection ^^'
I download the server v4.0.29.11263.exe from photon and after ? .. I'm lost ^^"

It's not about scripts conenction , just how to set up my server ^^
