1.2 Add vs.Commit vs. Push
Add:
- selects changes
- tells git to start tracking a file.
- If you modify a file after you run git add, you have to run git add again to stage the latest version of the file.
Commit:
- records changes LOCALLY
- saves the changes only to the local repository but not to the remote repository
- If you make any changes or even delete the files, you can still recover our committed files
Push:
- shares changes
- updates your committed changes and allows you to send them to the remote repository where all of the developers can access them
