Keybase installation instructions are wrong/incomplete, and installation fails (OS X 10.10.1)

Hi

I would like to raise some issues with the installation instructions. I understand that this is not even a beta, but an alpha, but nevertheless I followed these instructions to install it on my system (OS X 10.10.1) to try it out, but failed at the first hurdle:

srm@localhost:~$ node
> npm install -g keybase-installer
npm should be run outside of the node repl, in your normal shell.
(Press Control-D to exit.)

I didn't realise that although I had installed Node.js (using Macports) I did not install npm (Javascript package manager), which seems to be a prerequisite for installing keybase-installer, but is not listed as such on the Prerequisites page. It appears npm includes Node.js anyway. I have never used Node.js and knew nothing about npm prior to this.

So the issues I am raising (in relation to the installation instructions, which are clearly wrong) are as follows.

1. The user should be asked to download and install npm first (via Macports or directly from https://www.npmjs.com/, it shouldn't make any difference I think). This will automatically install the latest version of Node.js (v. 0.10.35) - I have checked that this is the case.
2. Then the user should be asked to install the "keybase-installer" via npm using sudo (otherwise it fails, because it needs su access to make directories in /usr/bin/lib/ etc.).
3. I think you have a naming issue, which makes it hard to understand the keybase architecture - you have an installer for keybase which is referred to in your repo as the node-installer for the node client [?] , and you have keybase itself which is referred to as the node client / terminal client for keybase.

In my case the keybase-installer installation fails, just after the unpacking stage it appears - here is my bash session output

srm@localhost:~$ sudo npm install -g keybase-installer

Review the command-line installation and prerequisites pages linked in the issue, then compare their Node.js/npm steps with the reported macOS session. Check the keybase-installer flow around the npm EACCES failure and naming confusion; done means the prerequisites, installation commands, and installer terminology accurately describe a working path or its required permissions.
