trying to install node.js and npm

I am trying to get Angular 2 up and running. The first thing it does is ask me to install node.js and npm.

So I've gone to https://nodejs.org/en/ and downloaded the msi, run it and gone through the install process.

Er... now what?

I go to my project folder and npm or sudo or any other node command is not recognized. Surely nodejs needs to be activated or something.

What gobsmacks me is that the nodejs site seems to assume I will just magically know the rest of the process. There's no instructions for actually installing or confiuring the thing. I guess I'm off to find some hand-rolled blog article from someone who's figured this out ahead of me?
