Workflow
- Local Repository Structure The local Git repository has three components:
1- working Directory: The actual files reside here.
2- Index: The area used for staging
3- Head: Points to the most recent commit
Saving Changes
- All files in a checked out (or working) copy of a project file are either in a tracked or untracked state.
1- Tracked
Tracked files can be modified, unmodified, or staged; they were part of the most recent file snapshot.
2- Untracked
Untracked files were not in the last snapshot and do not currently reside in the staging area.
*After cloning a repository, files have tracked status and are unmodified because they have been checked out but not edited.
