Git Intro

What is Git?

Git is a widely-used version control system created by Linus Torvalds in 2005 and maintained by Junio Hamano since then.

It is used for:

• Tracking code changes
• Identifying who made changes
• Facilitating coding collaboration

What does Git do?

• Manage projects using Repositories
• Clone a project to work on a local copy
• Control and track changes through Staging and Committing
• Use Branching and Merging to work on different parts or versions of a project
• Pull the latest project version to your local copy
• Push local updates to the main project
  

  Working with Git

• Initialize Git in a folder to create a Repository.
• Git then creates a hidden folder to track changes within that folder.
• Any changed, added, or deleted file is considered modified.
• You choose the modified files you want to Stage.
• Staged files are committed, prompting Git to save a permanent snapshot of those files.
• Git enables you to view the full history of every commit.
• You can revert to any previous commit.
• Instead of storing a separate copy of every file in each commit, Git tracks the changes made in each commit.
  

  Why Git?

  Over 70% of developers use Git!

  • Developers can collaborate from anywhere in the world.
  • They can view the complete history of the project.
  • They can revert to earlier versions of the project.

  What is GitHub?

  • Git is distinct from GitHub.
  • GitHub provides tools that utilize Git.
  • GitHub is the largest source code host globally and has been owned by Microsoft since 2018.
  • This tutorial will focus on using Git with GitHub.
