The mechanics come from my own notes to remember how to do the refactoring when I haven’t done it for a while. As such, they are somewhat terse, usually without explanations of why the steps are done that way. I give a more expansive explanation in the example. This way, the mechanics are short notes you can refer to easily when you know the refactoring but need to look up the steps (at least this is how I use them). You’ll probably need to read the examples when you first do the refactoring.
