The section that deals specifically with the behavior expected from players is Etiquette. This part of the game emphasizes the importance of respect for fellow players, the course, and the spirit of the game. It outlines the manners and considerations that players should uphold while playing, such as maintaining pace of play, repairing the course, and being courteous to others.

Etiquette is crucial because it helps maintain a positive environment that ensures everyone can enjoy the game. Players are expected to conduct themselves in a manner that reflects good sportsmanship, which is essential for fostering camaraderie and respect among competitors. Understanding and adhering to the principles of etiquette is as important as following the rules of golf in ensuring a fair and enjoyable experience for all participants.

The other sections, such as Definitions, Rules of Golf, and Principle Changes, focus more on the fundamental guidelines of play and the specifications of the game rather than the expected conduct between players.
