How to Convert a DFA to a GNFA?

[enginerd22]

TL;DR

Looking for resources that clearly explain how to convert a DFA to a GNFA.

So, I'm looking for resources that will teach me how to do the steps in the problem, mainly how to convert this to a GNFA.
My book doesn't even mention the GNFA, we just went over it briefly in class. When I do try to convert it as I understand, it is too complicated for me to know how to properly remove the node.
So, I'm not asking for answers, but any resources that will teach me how to do those two things. Thank you!

Here's a couple of web pages on it found via Google "DFA vs GNFA":
