What does Git do?

• Manage projects with Repositories
• Clone a project to work on a local copy
• Control and track changes with Staging and Committing
• Branch and Merge to allow for work on different parts and versions of a project
• Pull the latest version of the project to a local copy
• Push local updates to the main project

Working with Git

• Initialize Git on a folder, making it a Repository
• Git now creates a hidden folder to keep track of changes in that folder
• When a file is changed, added or deleted, it is considered modified
• You select the modified files you want to Stage
• The Staged files are Committed, which prompts Git to store a permanent snapshot of the files
• Git allows you to see the full history of every commit.
• You can revert back to any previous commit.
• Git does not store a separate copy of every file in every commit, but keeps track of changes made in each commit!

What is GitHub?

• Git is not the same as GitHub.
• GitHub makes tools that use Git.
• GitHub is the largest host of source code in the world, and has been owned by Microsoft since 2018.
• In this tutorial, we will focus on using Git with GitHub.
