Microsoft recently moved to git for version controlling Windows and Office.
I will not be able to cover everything relating to Git, it is an incredibly powerful tool.
However, hopefully I will be able to give you enough to get started and at least understand the
official documentation.

I am obviously not going to be able to go over everything that git does.
\begin{itemize}
\item I don't know everything Git does
\item Git does LOADS of stuff
\item Go through some basic operations to help you use git
\item Give you enough of a grounding to understand the official documentation
\end{itemize}
\note{%
I am obviously not going to be able to go over everything that git does because it does so much.
Hopefully after this you will be able to use Git well for most day-to-day tasks. Git has very
compressive documentation. I hope that this will also give you enough of a background to
understand the documentation.

The linear graph we just saw is an overly simplistic representation. In reality, Git
represents history using a Directed acyclic graph which allows parents to be shared my
multiple commits. This is useful because it allows for Branches. We will look at these a bit
more later.
It is good practice to develop features on a separate branch. This allows for multiple
people to work on a project as well as allowing things like bug-fixes to be deployed without
having to worry about interference from a new feature.

is smart enough to auto-merge branches although at times human intervention is necessary.
By default, git creates a branch called Master when you create a repository.

\item By default Git will create a branch called Master (maybe?).

\note{%
So, when I originally wrote this slide, git would create a branch called master by default.
The convention was that this was your "main" branch. Currently on my system it still does
although there is a movement to switch the default to main or primary or something similar.
I have no intentions to make this a political talk so make of it what you want.
