 In other words, signals are a mechanism that allows different parts of an application to communicate with each other by sending and receiving notifications when events occur.

+### Rules of use
 When using signals, try to adhere to these guidelines:
 1. Don't use signals when you can use another method, such as an override of `save()` or `__init__`.   
 2. Document its usage in this readme (or another centralized location), as well as briefly on the underlying class it is associated with. For instance, since the `handle_profile` directly affects the class `Contact`, the class description notes this and links to [signals.py](../../src/registrar/signals.py).
