Git for non-programmers 2
A couple of definitions
When you add changes with the
git add command you are adding to the

Why use a version control system (VCS)?
Have you ever tried to add a new feature to, or change (refactor) an
existing part of, a piece of software (or improve a section of a
document) and eventually realised that you made it worse and you
aren’t sure how to get back to where you started? Perhaps, to avoid
such a situation, you now have cluttered directories filled with
my-code-v2-plus-that-other-feature etc., etc. and you’re
not quite sure which one does what you want. Version control will help
you to keep a log of your changes as well as snapshots of the code as
you apply them; it will also allow you to collaborate far more easily
but, for now, we will focus on a single editor and a linear history.
