What is cycling etiquette?

Could you please explain what cycling etiquette entails? As someone who enjoys cycling, I'm interested in understanding the unwritten rules and behaviors that cyclists are expected to follow on the road. Is it simply abiding by traffic laws, or are there other aspects that contribute to SAFE and respectful cycling? Additionally, how do these etiquette guidelines differ depending on the type of cycling, such as road cycling, mountain biking, or even casual bike rides? I'm eager to learn more about this important aspect of cycling culture.
