Who are we ? (v2)

What is Git?

• "Open Source Distributed Version Control System"
• Created by Linus Torvalds
• It's an instrument that allows us to manage our code and  the history of its changes

Basic Git Terminology

1. COMMIT
2. HEAD
3. BRANCH

How it works?

1. Directed acyclic graph

2. Immutability

But first ... let's setup a REPO

What is GitHub?

• Web service from where we can access Git repositories
• Controlled access to repository by multiple people (contributors) with a nice UI over it
• Gives us a lot more tools like PR-s, Wikis, etc.

DEMO TIME

• add
• commit
• status
• reset
• checkout
• log
• reflog

Task
