Version control

Track changes

Share code

Facilitate collaboration

Go back in time

Without Version Control

How it works

Track all files in a directory (repository)

Identify line-by-line changes

Take snapshots of your files

Share to the cloud for collaboration

Git

Version control software

Free and open source

Enable new terminal commands

Industry standard

Locally

Initialize a project 

Add files to track

Take a snapshot/checkpoint of your work

git init

git add *

git commit -m "..."

Repeat these steps each time you make changes

git init

Run in the directory of your project

Creates a hidden .git file that track changes

Allows you to perform other git commands, like git status

git add

Adds files to be tracked in the future

Adds changes to already tracked files

One file (git add filename.r) or all files (git add *)

git commit

Takes a snapshot of added changes

Must include a message (git commit -m "message here") 

{but what's GitHub?}

git init

git add *

git commit -m "message"
