Before we start, let us see why we use git

The main concept is standardization

We need a coordinated way to work on our projects

But also for...

• To merge different sources
• To rollback to old status
• To work in offline mode
• and more...

Others motivations to know
how to deal with git

• Open source is moving forward thanks to git
  if you want to join it, you need to know git (GitLab, GitHub)
• git is an industrial standard
  several software platforms such as CI/CD tools rely on it,
  so a good knowledge is very appreciated in a curriculum
• Project edits are tracked (and optionally signed)
  you can blame who made the mistake
• ...these slides too are versioned with git
