When you want to remember what you did on your project, or see how it has changed over time, you can use Git to look back at all your saved snapshots. This is where the git log command comes in. Think of git log as a way to scroll through an album of your project's history. Each "photo" in this album is a commit—a saved change—with a message, the date, and a unique code that helps you find it later.

git log

To read the git log, start at the top. The long string after "commit" is the commit ID—a unique code for this snapshot. The Author line tells you who made the change. The Date line shows when it was saved. The message at the bottom explains what was changed in that commit. By reading these details, you can follow the story of your project and understand how it has grown, step by step.
