-TODO: modular component-based architecture, wrapping libMLV low level functions\
-      based on delegated click handlers and painting functions\
-      computing intermediate morphing between each frame, combined with a times, thus not using MLV_Animation
+The Graphical User Interface is designed with a modular component-based architecture. That architecture implies an
+Object-Oriented Programming's vision. Thanks to that, the application is very flexible for adding components and
+placing them. The components created are groups, buttons, and picture frames that are all based on a common structure
+called Component. Groups federate Components of any type and place them by a margin management.
+
+Thanks to a click handler and a printing function stored inside Components, it is possible to perform the actions on 
+click or to paint the component without knowing what is stored inside the group. The group is a component that handles 
+clicks and is able to paint itself by using the click handler and the painter function of the Component contained inside
+its list.  In other words, it delegates to the Components the action to perform. 
+
+It also wraps some libMLV low level functions to create basic application features that can be used to create coherent 
+state for the application and components. The rendering process is done by computing intermediate morphing between each 
+frame combined with a time. By this implementation, the application is not using MLV_Animation.
