 Welcome to the official documentation of the `Symfony Content Management Framework`_.
 
+The Symfony2 Content Management Framework  project is organized by the Symfony
+community and has several sponsoring companies and prominent open source leaders
+implementing the philosophy of the decoupled CMS. You can read learn more about the
+project on the about page.
+
 This documentation is currently in development and far from complete. See `Documentation planning`_ for an
 overview of the work left to do. Want to help? Thank you, all help greatly appreciated! The source of
 the `documentation is hosted here`_.
 
+Mission Statement
+-----------------
+
+    The Symfony CMF project makes it easier for developers to add CMS functionality to
+    applications built with the Symfony2 PHP framework. Key development principles for
+    the provided set of bundles are scalability, usability, documentation and testing.
+
+Why another CMS?
+----------------
+
+Actually we consider this project to be a CMF, a content management framework, rather
+than a CMS, a content management system. The reason is that we are only providing tools
+to build a custom CMS. There are obviously many CMS solutions available today already,
+but they tend to be tailored first and foremost towards end users and also many tend
+to carry a lot of legacy baggage which make them less than ideal for truly custom
+development like what is possible with `Symfony2`_.
+
+What is our target audience?
+----------------------------
+
+There are basically to main target audiences:
+
+ * Developers that have build a custom application with Symfony2 and just need to also
+   support a few content pages for things like the about/contact pages or a news section
+ * Developers that need to build a highly customized authoring and content delivery
+   solution that no out of the box CMS can properly provide through customization.
