Git is one of the most widely used version control tools, and is something that every developer should become comfortable with. In this course, 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.

To really test your understanding, you will complete four assessments that start with the core basics and go all the way up to advanced Git.

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

# The four stages of Git repositories

Recall the four stages of data in Git repositories:

# Visualizing the repository's history

Run these commands in which you look at the repository, and then make a disastrous mistake.

```Shell
1	git log
```
This shows you a default history of the repository. Page through it a few times by hitting space or down. You will see how far it goes back. Hit `q` to stop viewing it, and return to the command line.

```Shell
2	git log --oneline
```
Another way to view the log is one line per commit, which is much more concise and useful for many purposes. Obviously, some information is lost here.

```Shell
3	git log --oneline --graph
```
You've added the `--graph` flag, and now you get a visual representation of the history. Parsing this graph can be tricky; don't worry about understanding it exactly. But keep it in mind. It is helpful if you ever have to figure out what went on in a repository's past.
