    Why do we use Git?

    • Git is a first-class distributed version control system, so we use it to keep a record of changes to avoid loss-of-work and to appropriately explain/document changes as projects develop.
    • Git history, which is composed of “snapshots” of the source code, can be used to go back at any point in time, which leads to reproducible science.
