How to install node? or the required NPMs?

I think the deliverable would be to add an "Install" section to the main README.md file of this repo that lists every command needed to run (eg on a fresh Debian install) to:

1. install all required dependencies,
2. install this node session client,
3. create a session user account,
4. authenticate user account, and
5. send a message in the node session client

Ok, I've added additional details to the README, please review and let me know if that's sufficient

[maltfield]

Thanks! I think it's still missing the step where the user actually clones this repo and cds into it

Ok, added the CLI. I had just figured if you where on github, you'd know how you want to use it (via github client or GUI) but I can see how this is helpful. Let me know if there's anything else
