+# Barcode Scanner plugin for Phonegap #
+By Matt Kane
+
+## Adding the Plugin to your project ##
+Copy the .h and .mm file to the Plugins directory in your project. Copy the .js file to your www directory and reference it from your html file(s). You also need to add the ZXing library to your project.
+
+## Adding ZXing to your project ##
+First, [download the ZXing zip file](http://code.google.com/p/zxing/), unpack it, and put it somewhere safe such as your Documents folder. You'll need to whole package, not just the iphone folder. Then add it to your project, using the instructions in the zxing-1.x/iphone/README file. 
+
+## Using the plugin ##
+The plugin creates the object `window.plugins.barcodeScanner` with one method `scan(types, success, fail)`
+`types` is a comma-separated list of barcode types that the scanner should accept. If you pass null then any
+barcode type will be accepted. Currently only `QR_CODE` is supported, but that should change soon.
+
+`success` and `fail` are callback functions. Success is passed the decoded barcode as a string.
+A full example could be:
+
+    window.plugins.barcodeScanner.scan( BarcodeScanner.Type.QR_CODE, function(result) {
+            alert("We got a barcode: " + result);
+        }, function(error) {
+		    alert("Scanning failed: " + error);
+	    }
+	);
+
+
+## BUGS AND CONTRIBUTIONS ##
+The latest bleeding-edge version is available [on GitHub](http://github.com/ascorbic/phonegap-plugins/tree/master/iPhone/)
+If you have a patch, fork my repo and send me a pull request. Submit bug reports on GitHub, please.
