 ## Overview
 
 SideMenu is a simple and versatile side menu control written in Swift.
-- [x] **It can be implemented in storyboard without a single line of [code](#code-less-storyboard-implementation).**
-- [x] Four standard animation styles to choose from (there's even a parallax effect if you want to get weird).
-- [x] Highly customizable without needing to write tons of custom code.
-- [x] Supports continuous swiping between side menus on boths sides in a single gesture.
-- [x] Global menu configuration. Set-up once and be done for all screens.
-- [x] Menus can be presented and dismissed the same as any other view controller since this control uses [custom transitions](https://developer.apple.com/library/content/featuredarticles/ViewControllerPGforiPhoneOS/CustomizingtheTransitionAnimations.html).
-- [x] Animations use your view controllers, not snapshots.
-- [x] Properly handles screen rotation and in-call status bar height changes.

 ## Usage
 ### Code-less Storyboard Implementation
 1. Create a Navigation Controller for a side menu. Set the `Custom Class` of the Navigation Controller to be `UISideMenuNavigationController` in the **Identity Inspector**. Set the `Module` to `SideMenu` (ignore this step if you've manually added SideMenu to your project). Create a Root View Controller for the Navigation Controller (shown as a UITableViewController below). Set up any Triggered Segues you want in that view controller.
-![](etc/Screenshot1.png)
+![](https://raw.githubusercontent.com/jonkykong/SideMenu/master/etc/Screenshot1.png)
 
 2. Set the `Left Side` property of the `UISideMenuNavigationController` to On if you want it to appear from the left side of the screen, or Off/Default if you want it to appear from the right side.
-![](etc/Screenshot2.png)
+![](https://raw.githubusercontent.com/jonkykong/SideMenu/master/etc/Screenshot2.png)
 
 3. Add a UIButton or UIBarButton to a view controller that you want to display the menu from. Set that button's Triggered Segues action to modally present the Navigation Controller from step 1.

 That's it. *Note: you can only enable gestures in code.*

 - popWhenPossible: If a view controller already in the stack is of the same class as the pushed view controller, the stack is instead popped back to the existing view controller. This behavior can help users from getting lost in a deep navigation stack.
 - preserve: If a view controller already in the stack is of the same class as the pushed view controller, the existing view controller is pushed to the end of the stack. This behavior is similar to a UITabBarController.
 - preserveAndHideBackButton: Same as .preserve and back buttons are automatically hidden.
-- replace: Any existing view controllers are released from the stack and replaced with the pushed view controller. Back buttons are automatically hidden. This behavior is ideal if view controllers require a lot of memory or their state doesn't need to be preserved..
