This is the example project for @pengwinner's How to remember who made what when crediting project. Explore the inside of this project so you can get a better understanding of how to make a backpack project. For names you can't see, for example in the backdrop name it says 'Green line backd...', click it and use the arrow keys to go right and left to see the text.
