+# Appendix E - Git Tutorial
+
+![*Those were the good old days*](images\Chapter-Header\Appendix-E\old_days_2.png "Cartoon explaining the good old days")
+
+This is a tutorial for installing Git and Git-It tutorial on Windows 10 and macOS.  
+
+## Installing Git
+
+[Git](https://git-scm.org "Gits site") is a piece of software that allows for distributed version control.  Version control is an idea that started with giving a central repository for controlling access to source control. Version control is a way that all source code for a project can be stored in a central place.   With the rise of the internet, the concept of DVCS--distributed version control software, implemented the bring-over, merge, and modify model. Currently the industry standard VCS software is Git.  Git should not be confused with GitHub.  Git is the opensource version control software and GitHub is a commercial implementation of the Git software.
+
+Git can be installed on any operating system via an installer.  But I recommend to install it via a third party package manger.

+### Windows 10 - Chocolatey
