+Generally L looks for components in your Model/View or Controller directories.
+However for cases when you which to use an existing component and you don't need any
+customization (where for when you can apply a role to customize it) you may inject those
+components into your application. Please note any configuration should be done 'in the
+normal way', with a key under configuration named after the component affix, as in the
+above example.
+
+Using this type of injection allows you to construct significant amounts of your application
+with only configuration!. This may or may not lead to increased code understanding.
+
+Please not you may also call the ->inject_components application method as well, although
+you must do so BEFORE setup.
