 With iOS 7 you can easily create custom view controller transitions that can be used in a range of contexts (push, pop, modal …). This project provides a library of custom animations which can be dropped directly into your project. It also has a number of 'interaction controllers' which can be used with any of the custom animations in order to make your transitions interactive.
 
 The library currently contains the following animations, which can be made interactive with either a swipe or pinch gesture.

@@ -67,9 +61,9 @@ There are two key classes involved in a custom transition:
 
  + **Animation controller** - this class is responsible for performing the custom transitions. When you indicate that a custom transitions should be used, you provide an animation controller. This class performs the required animation, then informs the framework when it has completed.
  + **Interaction controller** - this class is responsible for managing interactive transitions - these are transitions that typically controlled by a gesture, allowing the user to swipe, pinch or perform some other action to navigate between view controllers. Importantly, interaction controllers allow transitions to be cancelled, i.e. a user can start the navigation, change their mind, and reverse it!

 **NOTE:** Animation and interaction controllers are entirely independent, this means you can wire up any interaction controller with any animation controller - which is pretty awesome.

 ## <a id="intro"></a>Adding custom transitions to your project
 
 This sections gives a brief overview of the steps required to add custom view controller transitions to your project. You might also want to look at the code for the demo app (in the `TransitionsDemo` folder) for reference. If you already know how the iOS 7 custom view controller transitions work, feel free to skip this section!
@@ -80,7 +74,7 @@ There are a couple of ways you can incorporate transitions from this library int
 
  1. **Cocoapods** - simply add a reference to **VCTransitionsLibrary** to your pod file.
  2. **Manual file copy** - if you are not using Cocoapods, you can simply copy the required files into your project. The `AnimationControllers` and `InteractionControllers` folders contain all the code that is required.
