+TFBarcodeScanner
+================
+
+Scan barcodes in iOS7 with elegance and ease
+
+![screenshot](https://raw.githubusercontent.com/thefind/TFBarcodeScanner/master/Screenshots/screenshot.png)
+
+iOS7 provides barcode scanning as part of the AV Framework, but it takes some work to
+figure it all out and then set it up to be efficient and robust. TFBarcodeScanner makes
+it super easy: create a view controller subclass of `TFBarcodeScannerViewController`,
+override `barcodeWasScanned`, and you are scanning barcodes!
+
+## Installation
+
+We recommend using CocoaPods to install TFBarcodeScanner. Add to your Podfile:
+
+    pod 'TFBarcodeScanner'
+
+To install manually, add TFBarcodeScanner to your project as a subproject, and
+then add the TFBarcodeScanner static library in your project's Build Phases.
+
+## Usage
+
+1. Create a view controller that is subclassed from `TFBarcodeScannerViewController`.
+   Make sure that your subviews have a transparent region so the preview is visible.
+1. In your `viewDidLoad` method, optionally set the `barcodeTypes` bit flag to whatever
+   barcode types you want to scan.
+1. Override the `barcodeWasScanned` method. This returns a set of barcodes that were
+   recognized. You normally will call `stop` once a suitable barcode is recognized.
+1. If you have UI elements that you want to overlay on top of the scanning preview,
+   override `barcodePreviewWillShowWithDuration` and show the elements in this method. You
+   will also want to override `barcodePreviewWillHideWithDuration` to hide these same
+   elements.
+
+See the Demo for sample code.
