Git and GitHub

# A branch is just a pointer 
Remember these points:

- A _branch_ is a pointer to the _end_ of a line of changes.
- A _tag_ is a pointer to a single change.
- `HEAD` is where your Git repository is _right now_.
- `Detached HEAD` means you are at a commit that has no reference (branch or
tag) associated with it.

# Is the `master` branch special?

It’s worth pointing out that apart from its default status, there is
nothing special about the `master` branch. It’s just a name. Your principal
branch might be called `live`, `alice`, `pristine`, `main`, or whatever you
like.

Quickly go over some important points from the previous lessons.
