+Extending / overriding existing styles
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+We cannot modify the order in which the application is reading the CSS. In
+the case we want to create new CSS style, the best is to define it a in a new
+CSS located under ``myapp/data/`` and use those new styles while writing
+customized views and templates.
+
+If you want to modify an existing CSS styling property, you will have to use
+``!important`` declaration to override the existing property. The application
+apply a higher priority on the default CSS and you can not change that.
+Customized CSS will not be read first.
