 # Getting Started With Chicken Bowling
 
-The AR Chicken Bowling App is a continuation of the AR Chicken Placement App to help users continue to build their skills and confidence with augmented reality. The AR Chicken Bowling App allows users to place spheres and chickens on their screen and explore how these nodes can interact with one another. Please note, no actual chicks are harmed in this project.

-A QR code should appear on your screen.  Open the App Inventor app on your mobile device and click “scan QR code”. Your app should appear on your mobile device. Time to use your app! Start by placing some chickens on your screen. Then, place a ball. You can pinch to make the ball bigger or smaller. Use the ball to try and knock over the chickens as if you are bowling! You can always use the reset button to clear your game. If the app can not find clear planes to place an item, you will receive an error message. If this occurs, try changing your location and moving closer to the location you want to place an item. Have fun playing with augmented reality and remember, no actual chickens are harmed in this project. Below are some ideas as to how you can expand and improve your app.
