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
