How can we increment a version file whenever developers change certain files?

We are trying to implement a solution that automatically increments a version file when developers update certain files:

• We see that there are options to use remote git hooks and other git hooks. We need guidance.*
• We want to be able to check in a script that does the replacement and have it execute under the specified condition.*
• We want to reduce/eliminate manual steps needed to set this up and hope it can just be checked in.*
• We have tried making a remote update hook. We are stuck adding the changed file in the bare git repo and re-pushing it. Is there a better way to do this?*
