Commit

A commit is a permanent snapshot of your entire project at a specific moment, saved in Git’s version history. Each commit records exactly which files changed, who made the changes, when they happened, and includes a short message explaining why. Commits are the building blocks of version control: they create an unbroken timeline of your project that you can navigate, compare, or roll back to at any point.

The Simple Version

A commit is like pressing “save” in a video game. It records the exact state of every file in your project at that moment. If anything goes wrong later, you can rewind to any previous commit and restore that version. Each commit includes a message (written by you) explaining what changed, like “add blog post about file organization” or “fix broken navigation link.”

Why It Matters

Commits are the backbone of version control. They create a timeline of your project’s history, making it easy to see what changed, when, and why. If a new feature introduces a bug, you can look at the commits to find exactly which change caused it and roll it back.

Good commit messages are important because they’re the story of your project. Six months from now, “fix mobile nav bug” is infinitely more useful than “update stuff.”

How It’s Used on This Site

Every meaningful change to this site gets its own commit. Blog posts, new features, bug fixes, design updates: each one is committed with a descriptive message. The full commit history lives on GitHub, creating a complete record of how the site evolved from its first line of code to today.
