 Gregwar's CaptchaBundle
 =====================
 
+[![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)
+
 The `GregwarCaptchaBundle` adds support for a captcha form type for the

+It uses [gregwar/captcha](https://github.com/Gregwar/Captcha) as captcha generator, which is a separate standalone library that can be used for none-symfony projects.
+
 Compatibility with Symfony
 ==========================
