Git and Version Control

Save clear checkpoints and collaborate with care.

Learn how project history, staged changes, diffs, branches, conflict review and releases help people work together. Practice with fictional web-project notes; commands are taught as concepts and are not executed inside the browser playground.

Course outcomes

• Explain the difference between a working copy, repository and checkpoint.
• Review status and stage only the intended safe changes.
• Read a diff and write a useful commit message.
• Keep focused work on a branch while it is reviewed.
• Resolve conflicts deliberately and retest the combined result.
• Prepare a release note and recovery plan without overstating verification.
