+Captcha
+=======
+
+![Captchas examples](http://gregwar.com/captchas.png)
+[![paypal](https://www.paypalobjects.com/en_US/i/btn/btn_donateCC_LG.gif)](https://www.paypal.com/cgi-bin/webscr?cmd=_s-xclick&hosted_button_id=YUXRLWHQSWS6L)
+
+Installation
+============
+
+With composer :
+
+``` json
+{
+    ...
+    "require": {
+        "gregwar/captcha": "1.*"
+    }
+}
+```
+
+Usage
+=====
+
+You can create a captcha with the `CaptchaBuilder` :
+
+```php
+<?php
+
+use Gregwar\Captcha\CaptchaBuilder;
+
+$builder = new CaptchaBuilder;
+$builder->build();
+```
+
+You can then save it to a file :
+
+```php
+<?php
+
+$builder->save('out.jpg');
+```
+
+Or output it directly :
+
+```php
+<?php
+
+header('Content-type: image/jpeg');
+$builder->output();
+```
+
+Or inline it directly in the HTML page:
+
+```php
+<img src="<?php echo $builder->inline(); ?>" />
+```
+
+You'll be able to get the code and compare it with a user input :
+
+```php
+<?php
+
+// Example: storing the phrase in the session to test for the user 
+// input later
+$_SESSION['phrase'] = $builder->getPhrase();
+```
+
+You can compare the phrase with user input:
+```php
+if($builder->testPhrase($userInput)) {
+    // instructions if user phrase is good
+}
+else {
+    // user phrase is wrong
+}
+```
+
+API
+===
+
+You can use theses functions :
+
+* **__construct($phrase = null)**, constructs the builder with the given phrase, if the phrase is null, a random one will be generated
+* **getPhrase()**, allow you to get the phrase contents
+* **setDistortion($distortion)**, enable or disable the distortion, call it before `build()`
+* **isOCRReadable()**, returns `true` if the OCR can be read using the `ocrad` software, you'll need to have shell_exec enabled, imagemagick and ocrad installed
+* **buildAgainstOCR($width = 150, $height = 40, $font = null)**, builds a code until it is not readable by `ocrad`
+* **build($width = 150, $height = 40, $font = null)**, builds a code with the given $width, $height and $font. By default, a random font will be used from the library
+* **save($filename, $quality = 80)**, saves the captcha into a jpeg in the $filename, with the given quality
+* **get($quality = 80)**, returns the jpeg data
+* **output($quality = 80)**, directly outputs the jpeg code to a browser
+* **setBackgroundColor($r, $g, $b)**, sets the background color to force it (this will disable many effects and is not recommended)
+* **setBackgroundImages(array($imagepath1, $imagePath2))**, Sets custom background images to be used as captcha background. It is recommended to disable image effects when passing custom images for background (ignore_all_effects). A random image is selected from the list passed, the full paths to the image files must be passed.
+* **setInterpolation($interpolate)**, enable or disable the interpolation (enabled by default), disabling it will be quicker but the images will look uglier
+* **setIgnoreAllEffects($ignoreAllEffects)**, disable all effects on the captcha image. Recommended to use when passing custom background images for the captcha.
+* **testPhrase($phrase)**, returns true if the given phrase is good
+* **setMaxBehindLines($lines)**, sets the maximum number of lines behind the code
+* **setMaxFrontLines($lines)**, sets the maximum number of lines on the front of the code
+
+If you want to change the number of character, you can call the phrase builder directly using
+extra parameters:
+
+```php
+use Gregwar\Captcha\CaptchaBuilder;
+use Gregwar\Captcha\PhraseBuilder;
+
+// Will build phrases of 3 characters
+$phraseBuilder = new PhraseBuilder(4);
+
+// Will build phrases of 5 characters, only digits
+$phraseBuilder = new PhraseBuilder(5, '0123456789');
+
+// Pass it as first argument of CaptchaBuilder, passing it the phrase
+// builder
+$captcha = new CaptchaBuilder(null, $phraseBuilder);
+```
+
+You can also pass directly the wanted phrase to the builder:
+
+```php
+// Building a Captcha with the "hello" phrase
+$captcha = new CaptchaBuilder('hello');
+```
+
+Complete example
+================
+
+If you want to see an example you can have a look at the ``demo/form.php``, which uses ``demo/session.php`` to
+render a captcha and check it after the submission
+
+Symfony Bundle
+================
+
+You can have a look at the following repository to enjoy the Symfony 2 bundle packaging this captcha generator :
+https://github.com/Gregwar/CaptchaBundle
+
+Yii2 Extension
+===============
+
+You can use the following extension for integrating with Yii2 Framework :
