Two short walkthroughs, depending on how much you want to see:

• Print the Sample Club Card - the fastest path: download a simple project, fill it in, print it. No editing.
• Customize and Print a Project from the Library - a more realistic path: find a project close to what you need, download it, put your own logo and business name on it, then print.

Either way, everything happens inside the Yatate app once you've imported a project - there's no account, no server, and no internet connection needed after the download.
