+# How we work - Open, Collaborative, Courageous, Caring
+
+In Equinor, [how we deliver is as important as what we
+deliver](https://www.equinor.com/en/careers/our-culture.html).
+
+As a values-based organization, our code of conduct for open source projects is
+simply a reflection of our values and how we live up to these as teams as well
+as individuals.
+
+This set the expectations for how we collaborate in our open source projects,
+and applies to all community members and participants in any Equinor maintained
+project.
+
+In addition to any definition or interpretation of the open source code of
+conduct, the company wide [Equinor code of conduct](https://www.equinor.com/content/dam/statoil/documents/ethics/equinor-code-of-conduct.pdf)
+always applies to all employees and hired contractors.
+
+## Handling issues within the communities
+
+We expect all to have a low threshold for raising issues, or in general discuss
+how we live up to our
+[values](https://www.equinor.com/en/about-us.html#our-values). Equally, we also
+encourage all community members to appreciate when concerns are raised, and make
+its best effort in solving them.
+
+As well as responsibility for what is delivered the project maintainers are also
+responsible creating an environment for proper handling of issues raised within
+the communities.
+
+## Call out for assistance
+
+For any problem not directly resolvable within the community, we encourage you
+to call out for assistance. Getting an outsiders perspective on the topic might
+be just what is needed for you to proceed.
+
+Send an e-mail to [[email protected]](mailto:[email protected]) and
+invite for a discussion. The email will be handled by a team within the Equinor organization.
+
+Your request will be kept confidential from the team or community in question,
+unless you chose to disclose it yourself.
+
+## Ethics helpline
+
+In Equinor, we want you to speak up whenever you see unethical behaviour that
+conflicts with our values or threatens our reputation.
+
+To underline this, we continuously encourage and remind our employees and any
+external third parties interacting with us to raise concerns or report any
+suspected or potential breaches of law or company policies.
+
+For any questions or issues that one suspect falls outside the scope of
+behaviour regulated, and handled within the open source code of conduct, or you
+wish to place an anonymous, confidential report we encourage to use the
+[Equinor Ethics helpline](https://secure.ethicspoint.eu/domain/media/en/gui/102166/index.html).
+
+This helpline is hosted by a third party helpline provider.
