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

This chapter covers the `git submodule`.

## Submodules

Submodules are a useful concept and often seen in real projects.

Git submodules can be very confusing if you stumble into them without much preparation or experience. Following this tutorial, you should have a good understanding of a simple submodule workflow and what is going on when you run the core submodule commands.

Submodules allow you to loosely link different Git repositories together so that they are bundled together. At the same time, it ensures that changing one will not break the other.

Sometimes, you want to include one repository in another but do not want to simply copy it over and have to maintain its changes separately. Submodules allow you to manage the separate codebase within your repository without affecting the other repository.

If this wasn't clear, re-read the above slowly. If it's still not clear, follow the example in the following lesson and see if it makes more sense.
