I need to move my files from the develop environment into master.
Could you be more specific when you talk about these files?
Do you mean, source file?
We use git. Therefore, you can use either git rebase or git merge:

https://git-scm.com/docs/git-merge
Several helpful tutorials explain both:

The choose is more oriented to your business; there is the right way on the situation.
