To get the most out of this book
All code examples in this book have been tested against WordPress 5.9 using the Twenty Twenty-Two theme, unless otherwise noted. As WordPress always strives for backward compatibility, they will likely work with future versions as well. All other software tools needed are covered in Chapter 1, Preparing a Local Development Environment.
If you are using the digital version of this book, we advise you to type the code yourself or access the code from the book's GitHub repository (a link is available in the next section). Doing so will help you avoid any potential errors related to the copying and pasting of code.
