Clone the repo.
Add a file called names.js containing the constant names which is set to a list of the names (as strings).
Add an image for each name to images/, where the filename for the image is of the form B_<name>.JPG.
(The name list and images are uncommitted, and their locations are .gitignored so that they are not shared.)
Open index.html in a browser. You will see a picture and four options. Click on the button for the name of the person shown and you will get a message indicating whether you were correct.
To see another image and choices, click the button labeled "Replay".
