Why Your Files Need a Story
See why a named history is more useful than a stack of final-final files.

This lesson works as a written guide with interactive examples. You can explore here before opening the real application or provider dashboard. A recorded video has not been added yet.
What will make more sense
- Recognize a checkpoint as a recorded project snapshot.
- Explain why a short reason helps a future reader.
One idea to keep
A useful file history records understandable changes with reasons.
The short lesson
Read the explanation at your pace
Imagine your business has a short description of its repair service. You improve the introduction on Monday, change the opening hours on Tuesday, and ask an assistant to make the tone friendlier on Wednesday. By Friday, somebody asks which change removed an important sentence. A clear history helps you investigate without relying on memory or a pile of files called final, final-new and final-really-new.
Git is a system that can record selected snapshots of files in a project folder. A recorded snapshot is called a commit. In this course we also call it a checkpoint to explain the idea. The important part is the relationship between a change and a short explanation. You can later look at what was recorded and read why the person making it thought the change belonged together.
Our practice business is fictional: Willow Workshop. Its service description is deliberately small. The starter folder contains service-before.md and service-after.md. These are ordinary readable examples, not a working Git repository. Opening them will not initialize history, connect an account or send your files anywhere. The browser activities teach the decisions before any optional real setup.
The prepared history has three entries: record the original description, clarify the booking instruction, and update Saturday hours. Each has one reason. Notice how that gives a later reader a useful story. An entry saying updated stuff would leave the reader guessing. A helpful record is useful to a future version of you as well as to a teammate or an assistant.
History does not judge the quality of the words. You can record an incorrect price just as easily as a correct one. That is why review comes before making a checkpoint. Look at the actual file, compare the proposed wording with the source, and decide whether it is ready. A neat history containing unreviewed mistakes is still a history of mistakes.
In the activity, choose the history entry that would help you understand a booking change next week. There is no command to memorize. Your first skill is recognizing why a change happened. When the assistant does more work for you, this small habit keeps the result understandable instead of turning the project into a mystery.

A tiny next step, if you want one
Optional: try 2 small actions at your own pace
You can finish this lesson by exploring the example above. These real-app actions are optional, and there is nothing to submit.
- Optional: open history-example.md and read its three fictional entries.
- Optional: open service-before.md in VS Code without changing it.

Does recording a checkpoint prove the content is correct?
If something looks different
The course folder does not show Git history.
That is expected. The download contains readable examples, not an initialized repository.
