Notes

• apt-get update has to be run first to get fresh list of packages to install
• apt-get install -y nodejs installs Node 4 😱 To get fresher Node need to follow these instructions https://askubuntu.com/questions/786272/why-does-installing-node-6-x-on-ubuntu-16-04-actually-install-node-4-2-6
• apt-cache policy nodejs returns available Node versions
