Topics

Code anywhere and everywhere with git

What is git?

• Git is a version control system (VCS). A VCS allows you to keep track of changes in a file (or groups of files) over time
• Git allows you to store code on different computers and keep all these different copies in sync

Why are we learning git in this class?

• Collaborate
• Share code ownership
• Work on larger projects
• Provide feedback on work in progress
• Learn professional software development tools

Git concepts

• repo (short for repository): a place where all your code and its history is stored

• remote repo: The repo created on github.com. You can access a remote repo via a browser (we’ll explore other ways later)

• In class demo:
  • creating a repo on github.com
  • adding collaborators to the repo
  • adding files to the repo
  • Updating files in a remote repo using a web browser
  • Viewing the version history
• cloning a repo: Once you have created a repo, you (and your collaborators) can copy (or clone) it on different computers. Each instance is now a local repo, because it exists on your (local) computer rather than the web.
• Using git command line tools, we can sync up different repos. This means multiple collaborators can work on the same code on different machines.
