 The next step is to define routes for our application. Let's create `AppRoutes.scala` in the following path, `oauth/src/main/scala/com/xonal/routes/AppRoutes.scala`.
 In this section we will define two routes, the first will show our landing page which will be static HTML and the second will handle the call back from GitHub after the user authorizes our Oauth application.

 This HTML page prompts the user to click the link to receive his or her GitHub details. The link contains a scope and client_id as URL parameters. When the user clicks the link, he or she will be directed to GitHub and asked to sign in if not already. The user will then be prompted to authorize our OAuth app with the defined scope, after which GitHub will redirect the user to the above callback route.

 The `ServerUtil` object contains the `oauthServer()` function which takes `Config` and `HttpRoutes[F]` as parameters and returns a `Resource[F, Server]`.
 We configure our server using `EmberServerBuilder` and pass it host and port values as `config.server.hostValue` and `config.server.portValue` respectfully. It also takes our `service` as a parameter through the `withHttpApp()` method.
