 ## Defining the content components

 We start by creating the components we want the router to render.
 
 Take a look at the `Settings` component. When it gets rendered by an [`Outlet`],
 it will render a second [`Outlet`]. Thus the second [`Outlet`] is nested within
 the first one, and will in turn render our nested content.

 ## Defining the root [`Segment`]

 Now we create the [`Segment`] that we will pass to the router.
 
 Note that we wrap `comp(Settings)` within a [`Route`]. For this exact code that
 is unnecessary, as this would be done automatically. However, in the next step
 we'll use a method of [`Route`], so we might as well add this now.
