+@section Code of conduct
+
+Be friendly and respectful towards others and third parties.
+Treat others the way you yourself want to be treated.
+
+Be considerate. Not everyone shares the same viewpoint and priorities as you do.
+Different opinions and interpretations help the project.
+Looking at issues from a different perspective assists development.
+
+Do not assume malice for things that can be attributed to incompetence. Even if
+it is malice, it's rarely good to start with that as initial assumption.

+Stay friendly even if someone acts contrarily. Everyone has a bad day

+once you are calm and without anger if you have to.

+If someone struggles do not put them down. Give them a helping hand
