Git is a system to show what changed between updates on a digital product. It's helpful
to see how a product changed, but also how to merge changes from multiple collaborators.
Let's say you have a book you are writing with a friend.
You write a chapter.
You write a second chapter.
You go back and add updates to the first chapter.
Your friend also made edits to the first chapter at the same time - uh oh!
How do we decide which changes to keep in the first chapter?
With Git, we can easily see what was modified: what was removed, changed, and added.
Now we can make the human decision to decide how to merge the changes.
What It Means For You
If you aren't a creator, you get two things from Git. The first is you can get updates instantly
by typing git pull into a command line. Neat! You can also see a full history
of everything single item that changed in a product. Even cooler.
