1. Create a new .js file in public/js/pieces/
2. Refresh or navigate to localhost:3000.
3. Your piece should show up in the pieces dropdown with the same name as the JavaScript file.
4. Click the piece in the dropdown and you will be navigated to localhost:3000/<piece name> which should display your piece.
5. At this point you can start modifying the JavaScript file you created to make your piece.

Art Blocks will pass you a tokenData object which will have an attribute called hash. You can access this value by typing tokenData.hash and manipulate it as you see fit.

Check out the example.js in the public/js/pieces folder for an applied example with comments.
