How to organize work in a Git repository if you regularly receive updated sources?

Question

git

I was given the project sources (only the source files, not access to a private repository). From these sources, I made my own repository in which I work with the code. In the original project, new versions of the sources are regularly released, changes from which I need to merge into my project. What is the best way to organize this? The project is huge with many thousands of files.

Answer 1

and how do extraneous sources differ from changes made manually?
- make a new branch of our repo
- delete everything from this branch
- copy third-party sources
- commit
- merge into the master
, as a result, extraneous changes are rolled into their own
