+## Quick Start Guide

+So you want to get up and tweeting as soon as possible?
+
+First, set up your authentication (you get this from twitter)
+```ruby
+Twitter.configure do |config|
+  config.consumer_key = YOUR_CONSUMER_KEY
+  config.consumer_secret = YOUR_CONSUMER_SECRET
+  config.oauth_token = YOUR_OAUTH_TOKEN
+  config.oauth_token_secret = YOUR_OAUTH_TOKEN_SECRET
+end
+```
+
+Second, tweet away!
+```ruby
+Twitter.update("I'm tweeting from the twitter gem!")
+```
+
+For more detailed information, keep reading!
