+Detect Language API Client [![Build Status](https://secure.travis-ci.org/detectlanguage/detect_language.png)](http://travis-ci.org/detectlanguage/detect_language)
+========
+
+Detects language of given text. Returns detected language codes and scores.
+
+## Installation
+
+Add this line to your application's Gemfile:
+
+    gem 'detect_language'
+
+Or install it yourself as:
+
+    $ gem install detect_language
+
+### Configuration
+
+Before using Detect Language API client you setup your personal API key.
+You can get it by signing up at http://detectlanguage.com
+
+If you are using Rails, create initializer `config/initializers/detect_language.rb` and add following code there.
+Otherwise just integrate following code into your apps configuration.
+
+    DetectLanguage.configure do |config|
+      config.api_key = "YOUR API KEY"
+    end
+
+## Usage
+
+### Language detection
+
+    DetectLanguage.detect("Buenos dias señor")
+
+#### Result
+
+    [ {"language"=>"es", "isReliable"=>false, "confidence"=>0.3271028037383178},
+      {"language"=>"pt", "isReliable"=>false, "confidence"=>0.08356545961002786} ]
+
+### Simple language detection
+
+If you need just a language code you can use `simple_detect`. It returns just the language code.
+
+    DetectLanguage.simple_detect("Buenos dias señor")
+
+#### Result
+
+    "es"
+
