How do I reconnect my project to my existing GitHub repository

问题

I am working on an Xcode project with source control. I messed up so I deleted the project from my laptop, and downloaded (ZIP) my own project which I pushed to GitHub earlier. But now this cloned project is not a git repository (or any of the parent directories): .git

Question: How do I reconnect my project to my existing GitHub repository?

回答1:

The easiest is to:

• clone your GitHub project
• cd in that local clone
• do a git --work-tree=/path/to/unzip/project diff to check if your zip has any differences with the version cloned from git hub: if it does, git add and commit. (and by that use git --work-tree=/path/to/unzip/project add -A . and then a simple git commit, to record the differences from the zip version of the project and the git cloned one)
• resume working with the local clone (which is a git repo)
