Provide usage documentation

No documentation makes this unusable for the uninitiated.

Yes - please: At least a short line with an example of what you mean by: Link and Code! Or an example QR Code. Thank You!

Is the Code the private Key? Please explain what information you should enter.

To get this app to work, you need to install the SparkleShare Dashboard.
Once you have that installed and working, you can easily use the QR code that it generates to configure the application.

This does need to be added to the information on the App Store and in the readme on github.
