Once installed on your device of choice, run the app and click the "About" icon in the navigation bar at the bottom of the app for usage instructions.
I hope the app is fairly intuitive so you can just start using it. But there are a lot of features that you'll never know about if you don't read the usage instruction, so take a few minutes when you have the time and look through the "About" screen.
