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

Let’s cover “off tags” really quickly while we’re here.
# Tags

Tags are the same as branches, except they do not have history. They point to a particular commit, but it doesn’t change (unless you force a change, or delete it).

# How to apply tags?

You can tag something where you are:

```Shell
1	git tag i_was_here
```

Or you can tag wherever a branch pointer is pointed at in your repository, even if you are not on it:

```Shell
2	git checkout e36355ed00ac3af009d7113a9dd281c269a79afd
3	git branch -f newfeature
```
The `-f` flag means `--force`. If a branch of `newfeature` already exists, then Git will not allow you to override it unless you use the `-f` flag.

```Shell
4	git checkout master
5	git tag remember_to_tell_bob_to_rewrite_this newfeature
```


What about Tags?
