6  - messages to be recorded in your own language with robot voice are explained with the Speakaloud function
7  - messages to be recorded in your own language with human voice are explained with the Speaktogoogle function
8  - birthdays and saint days of your family must be updated
9  - internet details must be updated
10  - callmebot API key must be updated
11  - update your email adress
12  - I have created an email adress for the robot (sender.email) you can do the same or use an existing email adress. 
13  - You must create a password for your email (receiver email) in your google account to accept emails from an application (https://fr.vittascience.com/learn/tutorial.php?id=1030/envoyer-un-mail-a-partir-d-une-carte-esp32)
