Uploading files to Waffle is a straightforward process. To get started, go to the "Files" tab inside your Toppings. There, you'll find a plus button that you can tap. This action will prompt you to choose the source of your files. You can select files from your photo gallery, pick files already stored on your device, or even capture new ones using your device's camera. Once you've made your selection, Waffle will efficiently upload your files, seamlessly integrating them into your Toppings for easy access and management.
