what is git?

  • You use Git to take snapshots of your code at points in time
  • Git keeps a history of what those snapshots look like
  • Git has a special label, called HEAD, that means “You Are Here
  • Usually you give a snapshot a label called a message

what is github?

  • A way to share code with others
  • It uses Git to help you manage your team’s work
  • An online place to store your code

what is a repository?

  • A repository is a collection of files that you’ve told Git to pay attention

> git status:

  • It will tell you what files have changed since your last commit. Right now, git is paying attention to 1 file (README.md)

> git add README.md:

-This tells git to include these changes in the next snapshot. Think of it as placing items into a scene to photograph

> git commit -m “Adds initial greeting to the world”:

-git commit is the shutter-button to take the snapshot -m specifies the message included with the commit Think of the message as being like a photo caption
