 ## Usage
 
-A simple usage example:
-
-```dart
-import 'package:dart_express/dart_express.dart';
-
-main() {
-  final app = express();
-
-  app.get('/', (req, res) {
-    res.json({
-      'hello': 'world',
-      'test': true,
-    });
-  });
-
-  app.listen(3000, (port) => print('Listening on port $port');
-}
-```
-
-Example with route parameters
-
-```dart
-import 'package:dart_express/dart_express.dart';
-
-main() {
-  final app = express();
-
-  app.get('/users/:userId/posts/:postId', (req, res) {
-    res.json({
-      'userId': req.params['userId'],
-      'postId': req.params['postId'],
-    });
-  });
-
-  app.listen(3000, (port) => print('Listening on port $port');
-}
-```
-
-With Body parsing Middleware:
-
-```dart
-import 'package:dart_express/dart_express.dart';
-
-main() {
-  final app = express();
-
-  app.use(BodyParser.json());
-
-  app.post('/post', (req, res) {
-    print(req.body);
-
-    res.send({
-      'request_body': req.body,
-    });
-  });
-
-  app.listen(3000, (port) => print('Listening on port $port');
-}
-```
-
-Using the mustache templating engine
-
-```dart
-import 'package:dart_express/dart_express.dart';
-
-main() {
-  final app = express();
-
-  app.use(BodyParser.json());
-  app.engine(MustacheEngine.use());
-
-  app.settings
-    ..viewsPath = 'custom_views_path'
-    ..viewEngine = 'mustache';
-
-  app.get('/', (req, res) {
-    res.render('index', {
-      'app_name': 'My Test App',
-    });
-  });
-
-  app.listen(3000, (port) => print('Listening on port $port');
-}
-```
-
-
-
-Listening to Https requests
-
-```dart
-  //listen for http requests
-  app.listen(port: 80, cb: (port) => print('listening for http on port $port'));
-
-  //assign certificate
-  var context = SecurityContext();
-  final chain = Platform.script.resolve('certificates/chain.pem').toFilePath();
-  final key = Platform.script.resolve('certificates/key.pem').toFilePath();
-
-  context.useCertificateChain(chain);
-  context.usePrivateKey(key);
-
-  //listen for https requests
-  app.listenHttps(
-    context,
-    port: 443,
-    cb: (port) => print('Listening for https on port $port'),
-  );
-```
