The pages directory contains a file for each page of the site.
components directory is where you will find all compoenents used across all pages. shared contains components used across multiple pages.
Any components specific to a page are grouped together in the same folder.
If a component has sub-components it conludes (i.e. footer) all of those components will be within the same folder.
We utilize Jest + Enzyme to unit test each component. Each component should be covered with a spec to ensure it renders without error as well any additional functions that component relies on to render correctly.
