 JungiThemeBundle
 ================
 
-The JungiThemeBundle is a themes engine designed for the Symfony2. It provides wide features which allows you to create
-flexible and smart themes with so-called tags. Thanks to these tags you can e.g. create a theme for desktop and mobile
-devices (Responsive Web Design) or create two separate themes where each one is designed for another device (Adaptive Web
-Design). Of course the functionality of the bundle not ends here. Read the documentation to know more.
