+# Git
+
+-------------------------------------------------------------------------
+
+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.
+
+-------------------------------------------------------------------------
+
+Programmer socks (not) included.
+
+-------------------------------------------------------------------------
+
+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.
+
+-------------------------------------------------------------------------
+
+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 in the audience asking...
+
+-------------------------------------------------------------------------
+
+Why not use SVN?
+
+-------------------------------------------------------------------------
+
+The answer is simple.
+
+-------------------------------------------------------------------------
+

+
+-------------------------------------------------------------------------
+
+An actual answer is that Git is Distributed, and SVN in centralized.
+
+-------------------------------------------------------------------------
+
+Simply put, devs can store their changes locally on their machines,
+
+-------------------------------------------------------------------------
+
+where 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.
+
+-------------------------------------------------------------------------
+
+Let's start with the basics.
