Setting Patient Instructions
In addition to the standard message text displayed when the patient takes some action a practice now has the ability to define some custom messages when a patient books an appointment. A practice can also define some helper text to be displayed to the patient on the home page about leaving messages and requesting repeats.

Here's the page that the practice uses to define the instructions:
