+Install
+=========================
+
+To integrate QR Code Encoder static library with your iOS application, follow the steps below:
+
+    1. Drag the Xcode project package QRCodeEncoderObjectiveCAtGithub.xcodeproj to your project navigator
+
+    2. Click on your project. Choose the target. Then go to the Build Phases page. Expand "Target Dependencies" and add qrencoder to the list
+
+    3. In the same Build Phases page, expand "Link Binary With Libraries", add libqrencoder.a to the list
+
+    4. Build the project and you are good to go!
+
+How to Use
+=========================
+    1. Import QREncoder.h
+
+    2. Call QREncoder +encodeWithECLevel:(int)ecLevel version:(int)version string:(NSString*)string to encode a string to a square matrix of booleans.
+
+    3. Call QREncoder +renderDataMatrix:(DataMatrix*)matrix imageDimension:(int)imageDimension to render the matrix generated from step 2.
+
+Take a look at QRCodeEncoderDemoViewController.mm for encoding and rendering examples.
+
+Also, since the encoder references C++ code, the implementation files need to have .mm as the extension.
