How to Use Git and GitHub

Lesson 1: Navigating a Commit History

In this lesson, you’ll learn about a few different types of version control systems and discover what makes Git a great version control system for programmers. You’ll also get practice using Git to view the history of an existing project. You’ll learn to see all the versions that have been saved, checkout a previous version, and compare two different versions.

Lesson 2: Creating and Modifying a Repository

In this lesson, you’ll learn how to create a repository and save versions of your project. You’ll learn about the staging area, committing your code, branching, and merging, and how you can use these to make you more efficient and effective.

Lesson 3: Using GitHub to Collaborate

In this lesson, you’ll get practice using GitHub or other remote repositories to share your changes with others and collaborate on multi-developer projects. You’ll learn how to make and review a pull request on GitHub. Finally, you’ll get practice by collaborating with other Udacity students to write a create-your-own-adventure story.

Project: Contribute to a Live Project

Students will publish a repository containing their reflections from the course and submit a pull request to a collaborative Create-Your-Own-Adventure story.
