 Obviously, if you **already** develop Ruby on OS X, a lot of this will be redundant, because you'll have already done it, or something like it. If that's the case, you may well be able to just install Ruby 2.0 using RVM and get started! Discourse has enough dependencies, however (note: not a criticism!) that there's a good chance you'll find **something** else in this document that's useful for getting your Discourse development started!
 
+## Quick Setup
+
+If you don't already have a Ruby environment that's tuned to your liking, you can do most of this set up in just a few steps:
+
+1. Install XCode and/or the XCode Command Line Tools from [Apple's developer site](https://developer.apple.com/downloads/index.action). This should also install Git.
+2. Clone the Discourse repo and cd into it.
+3. Run `scripts/osx_dev`.
+4. Review `log/osx_dev.log` to make sure everything finished successfully.
+
+Of course, it is good to understand what the script is doing and why. The rest of this guide goes through what's happening.

 ## UTF-8
 
 OS X 10.8 uses UTF-8 by default. You can, of course, double-check this by examining LANG, which appears to be the only relevant environment variable.

 ### Updating RVM
 
 If you do already have RVM installed, this should make sure everything is up to date for what you'll need.
@@ -78,28 +87,25 @@ Either way, you'll now want to install the 'turbo' version of Ruby 2.0.
 
 OS X comes with Git (which is why the LibXML2 dance above will work before this step!), but I recommend you update to Homebrew's version:
 
-    brew install git # 1.8.2 is current
+    brew install git # 1.8.5.3 is current
 
 You should now be able to check out a clone of Discourse.
 
 ### SourceTree
 
-Atlassan has a free GIT client for OS X called [SourceTree](http://www.sourcetreeapp.com/download/) which can be extremely useful for keeping visual track of what's going on in Git-land. While it's arguably not a full substitute for command-line git (especially if you know the command line well), it's extremely powerful for a GUI version-control client.

 ## Postgres 9.2
 
-**NOTA BENE** As I'm writing this, Postgres is known to have some sort of hideous security problem that is supposed to be patched Real Soon Now. Be careful!

 OS X ships with Postgres 9.1.5, but you're better off going with the latest from Homebrew or [Postgres.App](http://postgresapp.com).
