The example code in the files can literally be copied into your game at whatever point you need it. It is demonstrating exactly how to make the pronoun systems work. You can delete the dialogue lines or change the choice menu text. The important part is the variables which are changed with lines that start with $. There are lots of comments in pronoun_labels.rpy to explain what the lines are doing. Does that answer your question?
