+What Flask is, What Flask is Not
+--------------------------------
+
+Flask will never have a database layer.  It will not have a form library
+or anything else in that direction.  Flask itself just bridges to Werkzeug
+to implement a proper WSGI application and to Jinja2 to handle templating.
+It also binds to a few common standard library packages such as logging.
+Everything else is up for extensions.
+
+Why is this the case?  Because people have different preferences and
+requirements and Flask could not meet those if it would force any of this
+into the core.  The majority of web applications will need a template
+engine in some sort.  However not every application needs a SQL database.
+
+The idea of Flask is to build a good foundation for all applications.
+Everything else is up to you or extensions.
