+Routing in Flight is done by matching a URL pattern with a callback function.
+
+    Flight::route('/', function(){
+        echo 'hello world!';
+    });
+
+The callback can be any object that is callable. So you can use a regular function:
+
+    function hello(){
+        echo 'hello world!';
+    }
+
+    Flight::route('/', 'hello');
+
+Or a class method:
+
+    class Greeting {
+        public static function hello() {
+            echo 'hello world!';
+        }
+    }
+
+    Flight::route('/', array('Greeting','hello'));
+
+Routes are matched in the order they are defined. The first route to match a request will be invoked.
+
+## Method Routing
+
+By default, route patterns are matched against all request methods. You can respond to specific
+methods by placing an identifier before the URL.
+
+    Flight::route('GET /', function(){
+        echo 'I received a GET request.';
+    });
+
+    Flight::route('POST /', function(){
+        echo 'I received a POST request.';
+    });
+
+You can also map multiple methods to a single callback by using a `|` delimiter:
+
+    Flight::route('GET|POST /', function(){
+        echo 'I received either a GET or a POST request.';
+    });
+
+Method specific routes have precedence over global routes.
+
+## Regular Expressions
+
+You can use regular expressions in your routes:
+
+    Flight::route('/user/[0-9]+', function(){
+        // This will match /user/1234
+    });
+
+## Named Parameters
+
+You can specify named parameters in your routes which will be passed along to your callback function.
+
+    Flight::route('/@name/@id', function($name, $id){
+        echo "hello, $name ($id)!";
+    });
+
+You can also include regular expressions with your named parameters by using the `:` delimiter:
+
+    Flight::route('/@name/@id:[0-9]{3}', function($name, $id){
+        // This will match /bob/123
+        // But will not match /bob/12345
+    });
+
+## Wildcards
+
+Matching is only done on individual URL segments. If you want to match multiple segments you can use the `*` wildcard.
+
+    Flight::route('/blog/*', function(){
+        // This will match /blog/2000/02/01
+    });
+
+To route all requests to a single callback, you can do:
+
+    Flight::route('*', function(){
+        // Do something
+    });
