 is using a [personal fork] to [add a `FontCache` type] and
 [fix some issues with HiDPI].
 
+The implementation consists of different modules:
+  - __[`tour`]__ contains the actual GUI code: __state__, __messages__,
+    __update logic__ and __view logic__.
+  - __[`renderer`]__ implements a simple renderer for each of the used widgets on
+    top of the graphics module of [`ggez`].
+  - __[`widget`]__ re-exposes Iced's built-in widgets with the renderer type parameter
+    replaced with the implemented [`renderer`], for convenience.
+  - __[`main`]__ integrates Iced with [`ggez`] and connects the [`tour`] with
+    the [`renderer`].
