My problem is quite simple to understand but as I'm not familiar with git it's quite complicated to choose how to do and what's the best way to do it.
At the moment, I have v2.9.7 in production on which I did some adjustements to fit our needs.
I'd like to version my adjustements and be able to update PMF when a new tag is released on the official repo.
Here's what I started but maybe there's a better way to do it :
- Fork of the project.
- I cloned locally the tag 2.9.7 from my fork.
- I edited files to match my adjustements made on the 2.9.7 in production.
- I think here I might need to create a specific branch starting from that tag 2.9.7 as I guess I can't modify that tag to rename it 2.9.7-myname ?
And then I don't know what's the best way to continue...
I'll appreciate any advices

Thanks for your help
Regards
Fabien.
