+= ITunesSearchAPI
+
+Ruby interface to the ITunes Search API
+
+http://www.apple.com/itunes/affiliates/resources/documentation/itunes-store-web-service-search-api.html
+
+== Usage
+
+  ITunesSearchAPI.search(:term => "The Killers", :country => "US", :media => "music")
+  ITunesSearchAPI.lookup(:id => 284910350)
+
+See the API docs for more info on the parameters you can use to filter the search
+
+== Note on Patches/Pull Requests
+
+* Fork the project.
+* Make your feature addition or bug fix.
+* Add tests for it. This is important so I don't break it in a future version unintentionally.
+* Commit, do not mess with rakefile, version, or history. (if you want to have your own version, that is fine but bump version in a commit by itself in another branch so I can ignore when I pull)
+* Send me a pull request. Bonus points for topic branches.
+
+== Install
+
+ $ gem install itunes-search-api
+
+== Copyright
+
+See LICENSE for details.
