Introduction to Git and GitHub

In this module, you'll be introduced to the concept of version control, which will make managing and rolling back your code look super easy. You’ll learn how to differentiate between files and the tools at your disposal to make this happen. Next, you'll be introduced to Git and how you can leverage that platform to improve your coding abilities. Once you’ve got a grasp on what Git is, you’ll install it and start using it to create and clone code repositories. Last up, you’ll deep dive into Git in order to get more familiar with the different tools and commands it has to offer.

In this module, you’ll dive into advanced Git interactions by skipping the staging area for small code changes, and understand how Git uses the HEAD alias to represent checked-out snapshots. Next, you’ll explore how to move and remove files before finally getting a cheat sheet to help you in your Git explorations! The next step of your learning will include how to undo changes before committing and how to amend commits once they’re submitted. Finally, you’ll be able to identify errors in commits that were submitted a while back. In the final section of this module, you’ll explore the concept of branching and merging. You’ll learn what a branch is, how to create one, and how they work in harmony with you and your code. Once you’re comfortable with branching, you’ll dive into merging, how it works with branched data, and how to deal with merge conflicts.

In this module, you’ll be introduced to GitHub and learn how it works with Git. You’ll create new repositories and clone those repositories onto your computer. Next, we’ll explain what a remote repository is, how we can work with them, and how we can host them. You’ll get familiar with commands like modify, stage, and commit, which will be used for local changes, as well as the fetch command, which can pull any changes from remote repositories. Our final lesson will focus on learning about conflicts. This will allow you to explore the concepts of pull-merge-push workflows, pushing remote branches and rebasing your changes.
