 -   We set the `name` property to the namespace of the component. This tells the `ComponentContainer` control which UI component it should load and show.
 
--   We pass the `id` "walkthrough" to our component through the `ComponentContainer` constructor's settings argument. This `id` helps us identify our component among others that may be created during the application's runtime.

--   To ensure the `id` of our component is unique and avoid any mix-ups, we set the `autoPrefixId` property to "true". This automatically adds a prefix to the ID of the Component, which is the ID of the ComponentContainer followed by a single dash \("-"/).
