Hi, I just found out about Lightstreamers and I am attempting to create a Hello World page with Node.js following the totorial on Github. However there are several things I am confused about. Also to note, I am on a Linux Computer (Ubuntu)

-The tutorial fails to mention where I am suppose to save the helloworld.js file

-I don't understand how to run

node helloworld.The tutorial does not explain this, do I run this through terminal? Do I have to go to the directory of where "node" is installed? I also cannot run this through terminal because after starting the lightstreamer server through terminal, my terminal is "blocked" and new commands cannot run in it.
