Bootstrap4XPages is also an EXCELLENT reference for learning custom renderers. For my project-tracking app, I didn't use it directly, but I used much of the code either to save time or as a reference point for how I wanted to implement the Bootstrap theme I bought. Really helps you learn the platform all the more thoroughly.
