Git and GitHub

Online Courses

Git and GitHub LiveLessons (Workshop) is a fast-paced, engaging video course that teaches developers the essentials of Git and GitHub. You will learn the key commands to quickly become productive using Git and best practices for using GitHub to collaborate with your team.


Featuring live, step-by-step demonstrations, the lessons in this workshop cover:

  • Concise configurations—configuring just what you need to get the best out of Git
  • Your first repo—initializing a repo, three stage thinking, working with the staging area
  • Sharing your work—creating and configuring a GitHub repository
  • Additional activities—moving, deleting and ignoring files with Git
  • Building with branches—how to use feature branches effectively to work on projects. Includes merge types, merge conflicts and rebasing before merging
  • GitHub workflows—using clones, forks, feature branches and pull requests to collaborate effectively via GitHub
  • Releasing software—release tags, release branches and release workflows
  • How to undo anything—learn a range of powerful techniques, from git commit—amend through revert, reset, rebase—interactive and the famed reflog!
