+1. In order for your app to work when hosted in GH pages, you'll need to provide it with a page router. To do this, first install `react-router-dom` for your project.
+
+    ```shell
+    $ npm install react-router-dom
+    ```
+
+2. Wrap your `App` component in a `BrowserRouter` in your `src/index.jsx` or `src/index.tsx` file. For example, using typescript this would be:
+
+    ```diff        
+    +import { BrowserRouter } from 'react-router-dom';
+
+     const root = ReactDOM.createRoot(
+       document.getElementById('root') as HTMLElement

+     root.render(

+    +      <App />
