 - Trenette is based on web canvas, it requires a DOM canvas element to draw its content.
 
 - It is necessary for the canvas element width and height parameters to be properly configured since their values are used to process user input.
 
 - When using other DOM elements with the framework is also necessary to setup a DOM div to store these elements. (Booth the canvas and division should have the same position and size and should be aligned).
 
+- The code bellow shows how a canvas could be configured for a full screen setup.

+```javascript
 
+var canvas = document.createElement("canvas");
 
+canvas.style.width = "100%";
 
+canvas.style.height = "100%";
 
+canvas.style.top = "0px";

 - The `draw(context, viewport, canvas)` function is where the object gets draw into the screen, here you can implement your custom object as if it was drawn alone in a canvas.
 
 - The `transform(context, viewport, canvas)` is where the object matrix gets applied to the canvas drawing context, it is assumed that the viewport transformation was pre-applied.
 
 - Consider the point zero the origin of the object, every object has a position, rotation, scale and origin points used to control the object transform, these points don't need to be considered in the draw method.
