Git & GitHub

Built from the questions that actually get asked: viva and lab exams on version control, DevOps course papers, and the Git section of software-engineering interviews. Easy covers the everyday command surface; medium covers history rewriting and collaboration; hard covers the object model, reflog recovery, submodules and CI workflow semantics.
