How do I set up my Keurig K-Supreme Plus brewer for the first time?

First, remove packing tape and plug the brewer into a grounded outlet. Download the Keurig app, create an account, and scan the QR code on the back of the brewer. Follow the app instructions to connect to your home Wi-Fi, then press OK when you see the SUCCESS message. On the brewer, you'll see 'Wi-Fi Connected' - press FINISH. Finally, perform a cleansing brew by placing a large mug on the drip tray, filling the water reservoir to the max line, and following the on-screen instructions.
