Why version control?
====================

A functional quality software needs a version control system,
which provides several advantages.

    1. Record versions
        so that you can rollback the software to any history version.
    2. Collaboration between developers
        so that multiple developers can work simultaneously to enhance efficiency.
    3. Keep multiple braches
        so that software can be developed in a separate branch
        and it does not affect the stable (released) version.
    4. Code safety
        the approve-merge mechanism, etc.

`git`
=====
`git` is probably the most widely used version control system presently.
