Update the README

[gkoberger]

Took me a while to realize the steps were inside of nodester_auto.sh

curl -s https://raw.github.com/nodester/nodester-installer/master/nodester_auto.sh > nodester_auto.sh; 
chmod a+x nodester_auto.sh
./nodester_auto.sh

Also, I know an AMI is allegedly in the works, but a tutorial for setting things up on EC2 (presumably a popular option) would be awesome. Creating an instance and running the script worked pretty well (albeit some issues with n in my case), however the next steps (getting port 80 working, setting up a domain with it, etc) were a bit harder.

EDIT: Where are my manners!? Awesome script; worked like a charm. Thanks so much for all the work done on it so far :)
