Where do I find details on the applications we can add in droplet creation? I'm interested specifically in the 'node-v0.10.30 on Ubuntu 14.04' app. How was this built? How can I upgraded it when node 0.12 arrives?

npm cache clean -f
npm install -g n
n stable
To use the latest unstable release, you can run:
n latest
