Git Introduction

Git is a Distributed Version Control Systems (DVCSs).
Clients fully mirror the repository, including its full history.

Git thinks about its data more like a stream of snapshots.

Three Main File States

Git has three main states that your files can reside in:
committed, modified, and staged.

This lead us to the three main sections of a Git project: the Git directory, the working tree, and the staging area.

Three Git Project Sections

Basic Git Workflow:

1. You modify files in your working three.
2. You selectively stage just those changes you want to be part of your next commit, which adds only those changes to the staging area.
3. You do a commit, which takes the files as they are in the staging area and stores that snapshot permanently to your git repository.

Git Basics

1 Getting a Repository

1.1 Initializing a Repository in an Existing Directory

Bash example:

cd %my_project%

git init

This creates a new sub-directory named .git that contains all of your necessary repository files – a git repository skeleton.

git add *.c
git add LICENSE
git commit -m 'initial project version'

1.2 Cloning an existing repository

Bash command:

git clone <url>

This:
(1) creates a directory,
(2) initializes a .git directory inside it,
(3) pulls down all the data for that repository,
(4) and checks out a working copy of the latest version.
