I have a folder with an unknown version of a project versioned with git. The project in the folder (not versioned) have some minor changes that i would introduce in the main versioned project.
I know that the folder project started from a commit a point in the time that is in my versioned project.
I want to find the original starting commit, create a branch, apply the minor changes and then push up everything up to the master.
How can i do this? I can assume that some files has not changed so, is possible to find a version (commit sha) of a file?
