Description
--------------------
RuubikCMS is an open source website content management tool which is designed to be user-friendly for both the end-user and the webmaster. In our vision the end-user should be able to create and update webpages quickly without learning any special skills (no coding, HTML or CSS). For the webmaster a RuubikCMS site should be easy to install and manage but still flexible to allow modifications. In any case installing should be so easy that a designing oriented webmaster doesn't need any coding or database skills.
