[Just a quick note to Windows users.]
We use some git commands in the book. Some of you have reported problems when running them one Windows. Please note that when you run them in a DOS prompt on Windows, some special characters (like backticks) have a different meaning.
Fortunately there’s a simple way around that (as stated in the book’s intro, but that’s easy to miss): interact with Git through its Git BASH shell. That lets you avoid cross-platform issues and the commands will work as-is.
