Those are some of the questions that I will answer to you.

1) How do I make my patching process easier when I do have AG's?

2) I want to easily Backup/Restore my databases that are part of an Availability Groups. Is that possible?

3) I want to make sure that my AG's are healthy.

4) I am just tired of using Management Studio for checking my AG's. Can I make this easier?

You will see that adding Powershell to your life will make you work smarter not harder!
