Set up automatic email after file is updated?

I have no code writing experience what so ever so I apologize upfront about my ignorance regarding VBA. Just wanted to see if someone could help me out.

So, at my office we have a new document that I have been tasked with creating that outlines who/what a client does and any updates we have with them. I wanted to create a command that when the file is updated and saved on the drive, the user that makes the changes is prompted with the ability to send an email stating what they changed in the file (message body) to a specified user group.

I have found code that would do this from this site (but for word 2013 or earlier), but as a complete novice I have no way in knowing how to accurately implementing and making the above changes.

Let me know if anyone could help

cheers
