Missing steps in sections "Themes & Working With Fonts" and "Updating the User Input Field"

I’m reading this book for the first time now and working through the examples. I’ve found some missing steps and/or directions in the following sections of Chapter 5:

Themes & Working With Fonts
This one does not mention to the user that they need to copy over the res/values/font_certs.xml file.

Updating the User Input Field
This one doesn’t mention that you would first need to copy over the UserInput.kt file. And there are missing dependencies that cause it to not compile even if copied over.
