I am looking to implement a very basic version control at work with a team of 3 developers. I am looking to implement the following: https://stackoverflow.com/a/15487443/8876747 where we would have our own local repositories, make changes and push onto the shared drive. My only concern is overwriting.
What do I do in the case where we are working on the same piece of code/excel file (anything within the folder in general?) I assume if we just push our changes separately it will overwrite the first push, or the second push won't go through at all.
