Behave as a community member, follow the Code of Conduct.
The Fedora community is made up of a mixture of professionals and volunteers from all over the world, working on every aspect of the distribution from coding through to marketing. Diversity is one of our huge strengths, but it can also lead to communication issues and unhappiness. To that end, we have a few ground rules that we ask people to adhere to when they're using project resources. This isn't an exhaustive list of things that you can't do. Rather, take it in the spirit in which it's intended - a guide to make it easier to be excellent to each other.
When we disagree, we try to understand why. Disagreements, both social and technical, happen all the time and Fedora is no exception. It is important that we resolve disagreements and differing views constructively. Remember that we're different. The strength of Fedora comes from its varied community, people from a wide range of backgrounds. Different people have different perspectives on issues. Being unable to understand why someone holds a viewpoint doesn't mean that they're wrong. Don't forget that it is human to err and blaming each other doesn't get us anywhere, rather offer to help resolving issues and to help learn from mistakes.
