== Install Node.js and NPM ==

It is always a good idea to the upgrade and update before adding packages after the initial installation of the OS on the PI.
{{{
sudo apt-get upgrade
sudo apt-get update
}}}
You might need to removed the old nodered, which might not be the package we want
{{{
sudo apt-get remove nodered
sudo apt-get remove nodejs nodejs-legacy
sudo apt-get remove npm 
}}}
And then get the latest node source and install
{{{
curl -sL https://deb.nodesource.com/setup_4.x | sudo bash -
sudo apt-get install -y build-essential python-dev nodejs 
}}}
npm seems to come with nodejs.  When trying to do an apt-get install npm, I get an error.
Running with 
{{{

node --version
v4.4.5

npm --version
2.15.5

}}}


Here is an alternate way to install, but the above method seemed to work.
{{{
wget http://node-arm.herokuapp.com/node_latest_armhf.deb
sudo dpkg -i node_latest_armhf.deb
}}}

  It gives the most basic commands - none of the addons.  The section after integrating with slack works except for the pug me section. I found that the [https://github.com/Emile-Filteau/hubot-catme/blob/master/src/catme.coffee hubot-catme] section does work. And I didn't bother to understand the Jarvis part of the tutorial that talked about checking when a user was active last.  I went on with the example coffee script from the norrisbot git repository.
