+title:  "ZIO Code of Conduct"
+---
+
+We are committed to providing a friendly, safe and welcoming
+environment for all, regardless of level of experience, gender, gender
+identity and expression, sexual orientation, disability, personal
+appearance, body size, race, ethnicity, age, religion, nationality, or
+other such characteristics.
+
+The ZIO project follows the [Scala Code of Conduct](https://www.scala-lang.org/conduct/), with
+an additional clause regarding moderation that is detailed below. All participants, contributors and 
+members are expected to follow the Scala Code of Conduct when discussing the project on the available 
+communication channels. If you are being harassed, please contact us immediately so that we can support you.
+
+## Moderation and Steering Committee
+
+The ZIO project is moderated by the Steering Committee team members:
+
+- Itamar Ravid [@iravid](https://github.com/iravid)
+- John De Goes [@jdegoes](https://github.com/jdegoes)
+- Kai [@neko-kai](https://github.com/neko-kai)
+- Paul Shirshov [@pshirshov](https://github.com/pshirshov)
+- Pierre Ricadat [@ghostdogpr](https://github.com/ghostdogpr)
+- Salar Rahmanian [@softinio](https://github.com/softinio)
+- Wiem Zine El Abidine [@wi101](https://github.com/wi101)
+
+The ZIO project requires that drastic moderation actions detailed in the code of 
+conduct - for example, removing a user from the Gitter channel - be agreed upon
+a group of over 2/3rds of the steering committee.
+
+For any questions, concerns, or moderation requests please contact any member of
+the project, or the people listed above.
+
+## BDFL
+
+In addition to the above, the ZIO project's BDFL (benevolent dictator for life) is
+John De Goes (@jdegoes), owing to his original founding of the project and continued
+investments in it. While John adheres to the same code of conduct as everyone else,
+he is entitled to override moderation decisions made by the steering committee.
+
+We do not take the BDFL position lightly, especially with regards to moderation. John
+has consistently shown he is level-headed and able to handle conflict responsibly. Feel
+free to reach out to any member of the steering committee, including John himself,
+with any concern you might have.
