* Git is tool that's used in the programming industry.
* Another name for Git is a Version Control System (VCS) tool.
* Specifically to track project work done, and the changes to files we've made.
* The more correct term is Source Control.
* It is NOT a programming language.
* Git is a tool made for (usually) us programmers to track the work we've done.

Why Git
================================= =================================
Now we need to ask WHY. <!-- incremental_lists: true -->
* Now we need to ask WHY.
* Why would we need a tool like this?
* Why not use Google Drive instead?
* I will find your IP address.
* In all honesty,
* It's to help keep track of who did what.
* And to work on unique features...
* without affecting the main area/branch of our work.
* When DO we use git?
* Because Git keeps track of the changes we've made to files,
* We can then use it to commit and stage these files,
* and push them to a place where we can store them.

Code Storage
=================================
<!-- incremental_lists: true -->
* This place is called a Repository.
* Repositories are hosted on websites like GitLab, GitHub and Forgejo.
* But, an interesting feature of git, is that it allows you to time-travel.
* Meaning that if a project breaks, you can go back to before it broke.
* Now I hear you nerds in the audience asking...
* Why not use SVN?
* The answer is simple.

WHY don't we use SVN
================================= =================================
An actual answer is that Git is Distributed, and SVN in centralized. <!-- incremental_lists: true -->
* An actual answer is that Git is Distributed, and SVN in centralized.
* Simply put, devs can store their changes locally on their machines.
* Whereas on SVN they're stored on a central system.
* With a central system you NEED to be connected at all times to work on it.
* You can work locally on git without having to be connected,
* and then push once you're reconnected.
* Back to git.
