Steps for implementing React Router

• You'll notice we've already installed react-router-dom for you.
• import your BrowserRouter as Router inside your index.js file.
• Wrap your <App /> component that you're passing to ReactDOM.render() with your new Router component.
• open up your chrome REACT DEV TOOLS and notice your app is now all wrapped in BrowserRouter
• inside the REACT DEV TOOLS expand <BrowserRouter> and highlight <Router> and notice that here is a "history" object on props and a "match" object on its state. These two objects are how all of our Router is going to work.

Steps for "Declaring" your routes

• Inside of your App.js file import { Route } from 'react-router-dom';

• You should now be able to type /, /about, /contact after localhost:PORT/ to see what's a

Steps for setting up your Navigation

• Declare the to as the href on <Link> and specify the correct routes for your app to navigate towards.
• Head over to your app and start navigating. You should be able to see your URLS changing their paths as you go. Each path should display the proper component.
