+## Error Boundaries
+
+Components that have substantial state and internal functionality should be wrapped in an [Error Boundary](https://reactjs.org/docs/error-boundaries.html). This allows for catching unexpected errors and displaying a fallback UI.
+
+Components that are stateless views are unlikely to throw exceptions and don't require an error boundary.
+
+The `ComponentError` component is a pre-built error state that can be used to display an error message and a bug reporting button.
+
+### Example
+
+```tsx
+import { ErrorBoundary } from 'react-error-boundary';
+
+<ErrorBoundary
+      // eslint-disable-next-line react/no-unstable-nested-components
+      fallbackRender={({ error: e, resetErrorBoundary }) => (
+        <ComponentError
+          componentName="BrowserNotifyModal"
+          message={e.message}
+          retryFunction={resetErrorBoundary}
+        />
+      )}
+    >
+		<YourFunctionality/>
+</ErrorBoundary
+```
