+## Architecture
+
+### Routing
+
+[React Router](https://reactrouter.com/) handles the routing. 
+
+To avoid unnecessary [re-renders](/contributor/frontend/advanced/best-practices#managing-re-renders) all the routing logic is in a `useEffect` in `PageChangeEffect`.
+
+### State Management
+
+[Recoil](https://recoiljs.org/docs/introduction/core-concepts) handles state management.
+
+See [best practices](/contributor/frontend/advanced/best-practices#state-management) for more information on state management.
+
+## Testing
+
+[Jest](https://jestjs.io/) serves as the tool for unit testing while [Storybook](https://storybook.js.org/) is for component testing.
+
+Jest is mainly for testing utility functions, and not components themselves.
+
+Storybook is for testing the behavior of isolated components, as well as displaying the [design system](/contributor/frontend/basics/design-system).
