 If you have an idea, but you want to show it to someone before committing to it, git lets you make a copy of the project, then give someone your copy and your new ideas.  They can then make changes before putting it into the book.
 
+## Setup
+
+Setting up git it easy.
+Just install `git` with your package manager (probably `sudo apt install git`) then give it the same username and email as you use on Github.
+
+```bash
+git config --global user.name "Your Unchanging Name"
+git config --global user.email "email@eternal.tld"
+```
+
+You don't need to use your real name, but you do need to keep a consistent name and email.
+
+Your email will be public, and is used for people to ask why you made a particular change, in case your notes are not clear.
+If you're sure you don't want to use your real email address, use `bindrpg@posteo.uk` instead.
+
+## Basic Usage
+

 Make a new branch to play with, and name it something (in this example, your username).
