Git Introduction

Source Control

In a nutshell:

• It's really useful to save your code somewhere that isn't just on your local computer, in case your computer dies
• If all your code is somewhere where everybody can reach it, that means everybody can work on it together
• If you keep backups of what your code was like in the past, you can go back to it if you messed something up now.

Advanced:

• We call the code the "source code." Since we want to keep it under control (backed up, available, etc), we call solutions to this problem "Source Control."
• Source control systems such as Git or SVN let us easily back up our code and collaborate together
