 # AXPhotoViewer

This library supports contextual presentation and dismissal, interactive "flick-to-dismiss" behavior, and easily integrates with many third party async image downloading/caching libraries. 
+AXPhotoViewer is an iOS photo viewer that is useful for viewing a very large (or very small!) amount of images and GIFs. This library supports contextual presentation and dismissal, interactive "flick-to-dismiss" behavior, and easily integrates with many third party async image downloading/caching libraries.
 
 While AXPhotoViewer has many configurable properties on each of its modules, it is easy to throw down some initialization code and get started:
 
 ```swift
 let dataSource = PhotosDataSource(photos: self.photos, prefetchBehavior: .regular)
 let pagingConfig = PagingConfig(navigationOrientation: .horizontal)
-let transitionInfo = TransitionInfo(startingView: self.startinImageView) { [weak self] (photo, index) -> UIImageView? in
+let transitionInfo = TransitionInfo(startingView: self.startingImageView) { [weak self] (photo, index) -> UIImageView? in
     return self?.endingImageView
 }
-        
+
 let photosViewController = PhotosViewController(dataSource: dataSource, pagingConfig: pagingConfig, transitionInfo: transitionInfo)
 self.present(photosViewController, animated: true, completion: nil)
 ```
 
+### Objective-C interoperability
+This library fully supports interop between Objective-C and Swift codebases. If you run into any issues with this, please open a Github issue or submit a pull request with the suggested changes.
+
+### Installation
+Installation can easily be done through Cocoapods:
+```ruby
+pod install 'AXPhotoViewer', '~> 1.0.0-beta.5'
+```
+or, if you prefer not to use Cocoapods, add the contents of the 'Source' directory to your project to get started.
+
+More info to come.
