Step-by-step Automation server Guided learning

Hi everyone; Two months ago, I started my journey down the rabbit hole of shortcuts and home automation. So far, it has been a real pleasure.

To commit myself to go deeper I purchased The lifelong license for the automation server.

I realize that I might miss my conditions for optimized learning.

Has anyone some Step-by-step manual which I can replicate in order to understand better what and how to work with this service?

One question to kick it off:
What settings have been proven to work best for the dedicated server phone.
Can I mute the phone and turn of notifications?

Any help and simplified explanations are highly appreciated - Since I have no background in any IT related topics.

I hope to share my future inventions with you once I managed the “understanding part” of it.
