In this module, you will get hands-on experience working with Git and its advanced concepts.

DevOps for Developers

Git is one of the most widely used version control tools, and is something that every developer should become comfortable with. In this module, you will get hands-on experience working with Git so that when it comes time to use it, you’ll be ready.

You’ll start by learning some of the more fundamental concepts such as initializing a Git repository, adding files to a repository, and how to commit changes. You’ll also learn how to clone a repository, and how to create branching.

You’ll then make your way to some more advanced concepts like Git stash, cherry-picking, working with multiple repositories, pushing code, and a lot more.

By the end of this module, you will have a proficient and working knowledge of Git which will serve you well throughout your career.

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.
