How to set up my windows azure account to support node js scripts?

I have been able to run the node js scripts on my local emulator thanks to iisnode. But when i publish my project to windows azure, the node js scripts dont work. Do i have to set up something on my azure to get the node js scripts running, like installing iisnode or node js on azure? I was guessing they would be installed by default. I am pretty new to windows azure, please guide me on how i can run the node js scripts on my azure cloud platform.

EDIT: https://www.windowsazure.com/en-us/develop/nodejs/tutorials/create-a-website-(mac)/

Above article says that the platform should have a working installation of Node.js and the Windows Azure SDK for Node.js, so i guess they are not installed by default on the azure?. Any idea on how i can check that? or even how i can install them? By RDP into my role instances or by some way through the azure management portal?
