Intro to how shortcuts work
When you run a shortcut, each action in the list of actions runs in order from top to bottom. Each action plays a role in the task you want to accomplish, much like individual steps in a factory assembly line. For example, some actions fetch information either from your device or from the Internet. Some actions transform information — for example, resizing an image. Other actions share information to shared photo albums, to contacts using the Messages or Mail apps, or to other social media services.
