 QRite
 =====
 QRite is an Android application for generating QR code vCards or custom QR codes easily.
-You can customize size and color of the QR code, save it to your gallery and/or send it to an Android wear
-smartwatch.
+You can customize size and color of the QR code, save it to your gallery and/or send it 
+to an Android Wear or Pebble smartwatch. It has a much improved user-interface with a clean
+and minimal look.
+
+**_Note_**: As of now, this project is a work-in-progress and the code quality may be pretty bad
+Do not hesitate in submitting patches and correcting me if something seems really weird ;)

+Features
+--------
+You can either choose to input your details for generating a vCard of just input any arbitrary text 
+(such as a URL for your business or a link to a product info page or a coupon etc.) During or after 
+the generation of the QR code, you can customize its size and color based on some presets.
+
+*QR Code vCards* : You name, phone number and email are the only supported fields as of now so as to keep
+the QR code easily legible to readers. This is also the minimum info you may want to give a new 
+acquaintance contacts so that they can further ask you for details if needed.
+
+*Custom Text* : If you do not wish to submit a detail but have a URL or custom text to share, 
+you can use this field too. There are no restrictions on text in this field. So, remember Obi-wan, 
+choose wisely :)
+
+*Recent QR Codes* : The last 5 generated QR code info is saved so that you can quickly access it, in case 
+you need to generate a QR code. Select the small icon on the top right of the app on the main screen
+to access these recent items.

+*Customization* : You can choose from some presets or specify a custom size (less than 1024px) for 
+the QR code. You can also choose the colors from some available presets. This customization can also 
+be done once the QR code is generated using the Qrench menu on the top right in the QR code screen.
 
 TODOs

+Patches, pull-requests for bugfixes, new features or code contributions to refactor my naïve 
+Java coding attempt are very welcome :) To implement the smartwatch feature, I also need 
+an Android Wear device and a Pebble. If you happen to have one and don't need it anymore, 
+I would be happy to accept it. Or, consider buying the paid version of this app to support
+development and help me buy one. You can also tip me on Gratipay
