 HHRouter
 =====
-Yet another URL Router for iOS. Clean, Fast & Powerful.
+Yet another URL Router for iOS. Clean, Fast & Flexable. Inspired by [ABRouter](https://github.com/aaronbrethorst/ABRouter) & [Routable for iOS](https://github.com/usepropeller/routable-ios).
 
 ## Usage
 
+### Warm Up
+
+Map URL patterns to viewController. Better in AppDelegate.
+
+```objective-c
+[[HHRouter shared] map:@"/user/:userId/" toControllerClass:[UserViewController class]];
+```
+Define a `NSDictionary` property named `params` in viewControllers. Better in your BaseViewController.
+
+```objective-c
+@interface UserViewController : UIViewController
+@property (strong, nonatomic) NSDictionary *params;
+@end
+```
+
+### Exciting Time
+Get viewController Instance from URL. Params will be automatic parsed.
+
+```objective-c
+UIViewController *viewController = [HHRouter shared] match:@"/user/1/"];
+```
+
+`viewController` will be an instance of UserViewController. And `viewController.params` will be `@{ @"route": @"/user/1/", @"userId": @"1"}`.
+
+### URL Query Params
+
+URL Query Params is also supported. This will make things VERY flexable.
+
+```objective-c
+UIViewController *viewController = [HHRouter shared] match:@"/user/1/?tabIndex=3"];
+```
+
+`viewController.params[@"tabIndex"]` would be `3`.
+
+### One More Thing
+
+If your app has defined some url schemes, HHRouter will know.
+
+In the HHRouterExample Project, `hhrouter://user/1/` and `/user/1/` map to the same UIViewController.
