 ### Overview
 
-img.ly SDK provides tools to create photo applications for iOS with a big variety of filters that can be previewed in real-time. Unlike other apps that allow live preview of filters, img.ly SDK provides high-resolution images. With version two we were able to remove any resolution limits. Above that it's easy to customize the look of the app using Xcode's interface builder.
+img.ly SDK provides tools for creating photo applications for iOS with a big variety of filters that can be previewed in real-time. Unlike other apps that allow a live preview of filters, the img.ly SDK even provides a live preview when using high-resolution images. Version 2.0 removes any resolution limits, is written in Swift and allows for easy customization.

+### Adding a custom editor
+
+You can easily create your own sub editors by subclassing `IMGLYSubEditorViewController`. The main editor automatically passes a deep copy of the fixed filter stack, a low resolution image, and a completion handler to each sub editor. Each subclass also has an `UIImageView` called `previewImageView` that is used to present the preview image and an `UIView` called `bottomContainerView` that you can use to present your own controls. Within your subclass you should modify the passed `fixedFilterStack` and update the preview image whenever necessary by using `updatePreviewImageWithCompletion(completionHandler:)`. Finally, if the user taps the Done button, the updated fixed filter stack is passed back to the main editor, if the user taps the Cancel button, the updated fixed filter stack and simply discarded. You also have to add a new `IMGLYActionButton` to the `actionButtons` property of `IMGLYMainEditorViewController`.
