-node-install-script
-===================
+# Automated node.js installers for OS X and Ubuntu
 
-A script to install basic development tools for node (git, node, gcc, etc)
+A script to install basic development tools for node.js - git, node, gcc, pkg-config, etc
 
-Works for any recent version of Ubuntu or OS X.
+Pick one:
+
+* [OS X](#apple-os-x)
+* [Ubuntu Linux](#ubuntu-linux)
+* [TL;DR](#tldr)
+* [Important Notes](#other-things-you-should-know)
+
+## Screencast
+
+[How to Setup a VPS for node.js Development](https://www.youtube.com/watch?v=ypjzi1axH2A) - [(3:06 installing node.js](https://www.youtube.com/watch?v=ypjzi1axH2A#t=186))
+
+## TL;DR
+
+If you kinda know what you're doing already:
+
+**node.js + dev tools**
 
 ```bash
-# Specify the version of node to install
-echo "v0.11.14" > /tmp/NODE_VER
-
-# And install away!
-curl -fsSL bit.ly/easy-install-node | bash
+echo "Current node.js version is $(curl -fsSL https://nodejs.org/dist/index.tab | head -2 | tail -1 | cut -f 1)"
+curl -fsSL bit.ly/iojs-dev -o /tmp/iojs-dev.sh; bash /tmp/iojs-dev.sh
 ```
 
-**For older versions of Ubuntu**:
+**node.js only** (no git, gcc, etc)
 
 ```bash
-wget -nv bit.ly/easy-install-node -O - | bash
+# To install a specific version rather than defaulting to latest
+# latest version at time of writing are v1.8.4, v2.5.0, and v3.1.0
+echo "v2.5.0" > /tmp/IOJS_VER
+
+# node.js without development dependencies
+curl -fsSL bit.ly/iojs-min | bash
+
+# Ubuntu without curl
+wget -nv bit.ly/iojs-min -O - | bash
 ```
 
+## Apple OS X
+
+First you need to **Install XCode Command Line Tools**
+
+```bash
+xcode-select --install
+```
+
+Then you need to **Accept the XCode License** by running any command installed by Xcode with sudo. We'll use git.
+
+```bash
+sudo git --version
+```
+
+You can scroll to the bottom by hitting shift+G (capital G).
+
+Type `agree` and hit enter to accept the license.
+
+Now you can install node.js
+
+```bash
+curl -fsSL bit.ly/iojs-dev -o /tmp/iojs-dev.sh; bash /tmp/iojs-dev.sh
+```
+
+*TODO*: Make it easier to accepting the license (automatic?)
+
+## Ubuntu Linux
+
+```bash
+wget -nv bit.ly/iojs-dev -O /tmp/iojs-dev.sh; bash /tmp/iojs-dev.sh
+```
+
+## Other things you should know
+
 This is what gets installed:
 
-* fail2ban (not necessary for development, but should be on every server)
 * rsync
 * curl
 * wget
 * git
 * xcode / brew / build-essential / pkg-config / gcc
-* node
+* node (including npm)
 * jshint
 
-Screencast
-==========
+**NOTE**: If `fail2ban` is not already securing ssh, you will be asked to install it.
