+# Code of Conduct
+
+The Code of Conduct governs how we behave in public or in private
+whenever the project will be judged by our actions.
+We expect it to be honored by everyone who represents the project
+officially or informally,
+claims affiliation with the project,
+or participates directly.
+
+We strive to:
+
+* **Be open**: We invite anybody to participate in any aspect of our projects.
+  Our community is open, and any responsibility can be carried
+  by any contributor who demonstrates the required capacity and competence.
+* **Be empathetic**: We work together to resolve conflict,
+  assume good intentions,
+  and do our best to act in an empathic fashion.
+  By understanding that humanity drops a few packets in online interactions,
+  and adjusting accordingly,
+  we can create a comfortable environment for everyone to share their ideas.
+* **Be collaborative**: We prefer to work transparently
+  and to involve interested parties early on in the process.
+  Wherever possible, we work closely with others in the open source community
+  to coordinate our efforts.
+* **Be decisive**: We expect participants in the project to resolve disagreements constructively.
+  When they cannot, we escalate the matter to structures
+  with designated leaders to arbitrate and provide clarity and direction.
+* **Be responsible**: We hold ourselves accountable for our actions.
+  When we make mistakes, we take responsibility for them.
+  When we need help, we reach out to others.
+  When it comes time to move on from a project,
+  we take the proper steps to ensure that others can pick up where we left off.
+
+This code is not exhaustive or complete.
+It serves to distill our common understanding of a
+collaborative, shared environment and goals.
+We expect it to be followed in spirit as much as in the letter.
