Problem with HHVM

Hey,

I did follow the instructions i got here ( https://github.com/facebook/hhvm/wik...n-Ubuntu-14.04 )

And installed HHVM on Ubuntu 14.10.
So, i believe..
If i just enter hhvm to test it i get "Nothing to do. Either pass a .php file to run, or use -m server".
I also tested a hello world.php file and it did work.

There are many tutorials for hhvm online and after compiling and installing it. I tried to follow them.
This commando, * $ sudo /usr/share/hhvm/install_fastcgi.sh i tried to execute it but the file is not existing. This hhvm directory as a whole isnt existing.
Well, to me it seems like hhvm is ruing but i am not sure how to configure it. Because, the directories they are talking about in the tutorials are not existing.
So, i tried the find and locate functions but thats not working as well.

This is the first time i use a Linux server and the first time that i compile something.
I am quiet happy that i managed to get it somehow ruing but now i am not sure how to proceed with it.

Thanks for reading my silly problem.
