+# Application Architecture
+
+## Local Storage Integration
+The `useStorage` hook integrates with the browser's localStorage api.
+It accepts a localStorage key as its only argument and returns a state
+variable and setter function for that state variable. The hook enables
+bidirectional data transfer between tabs via an event listener that
+is registered with the Web Storage api.
+

+
+The `useStorage` hook currently lives in the `AppContainer` component. It
+can be relocated to a more general location should and if the need
+ever arise
+
+## Session Expiration
+Session timeout state is communicated to the client in the HTTP(S)
+response headers. Every HTTP(S) response is intercepted to read the
+session expiration time before being passed into the rest of the
+application. A timeout date is computed from the intercepted HTTP(S)
+headers and is pushed into local storage, where it can be read using
+standard Web Storage apis or other utilities, such as `useStorage`.
