ALT The image shows an analogy for the git workflow using letters. When you're working on the contents of your letter, you have unstaged changes. When you're ready, you'll add the letter to an envelope, and that's the equivalent of adding files to your staging area. Finally, you'll commit your changes by closing the letter and adding a stamp on it. After all that, you still need to push your changes to the remote repository, which is the equivalent of pushing your letter into a mailbox.
