+# Scikit-Optimize Code of Conduct
+
+Scikit-Optimize is an engaged and respectful community made up of people
+from all over the world. Your involvement helps us to further our
+mission.
+
+The goal of scikit-optimize is to become the go to project for black box
+optimization, freely available to the reader and everyone else. As any other
+open source project, it requires a community of people who maintain and
+contribute to it. The quality of the project depends on the engagement and
+size of the community; thus you as a user of skopt directly benefit from
+creating positive environment that encourages people to contribute to the
+project.
+
+To ensure that we build the best possible environment for our community, we
+introduced this code of conduct. When these guidelines are not followed, it
+can be detrimental to the community, and in turn not beneficial to the users of
+scikit-optimize.
+
+We receive contributions from people all over the world., this implies
+diversity of ideas and perspectives on often complex
+problems. Disagreement and healthy discussion of conflicting viewpoints is
+welcome: the best solutions to hard problems rarely come from a single angle.
+But disagreement is not an excuse for aggression: humans tend to take
+disagreement personally and easily drift into behavior that ultimately degrades
+a community. This is particularly acute with online communication across
+language and cultural gaps, where many cues of human behavior are unavailable.
+We are outlining here a set of principles and processes to support a
+healthy community in the face of these challenges.
+
+Fundamentally, we are committed to fostering a productive, harassment-free
+environment for everyone. Rather than considering this code an exhaustive list
+of things that you can’t do, take it in the spirit it is intended - a guide. We
+encourage you not to read this like a legal text that tries to solve every
+possible event, instead use common sense for the parts where there are gaps. It
+doesn't mean that application of this COC is going to depend on who you are or
+who you are friends with.
+
+Importantly: as a member of our community, *you are also a steward of these
+values*.  Not all problems need to be resolved via formal processes, and often
+a quick, friendly but clear word on an online forum or in person can help
+resolve a misunderstanding and de-escalate things.
+
+However, sometimes these informal processes may be inadequate: they fail to
+work, there is urgency or risk to someone, nobody is intervening publicly and
+you don't feel comfortable speaking in public, etc.  For these or other
+reasons, structured follow-up may be necessary and here we provide the means
+for that: we welcome reports by emailing
+[*Tim Head*](mailto:[email protected]) (a maintainer of
+scikit-optimize) or [*Kyle Kelly*](mailto:[email protected]) or [*Abby Cabunoc Mayes*](mailto:[email protected]) (who are both independent of scikit-optimize).
+
+This code applies equally to founders, developers, mentors and new community
+members, in all spaces managed by scikit-optimize. This
+includes the mailing lists, our GitHub organizations, our chat rooms, in-person
+events, and any other forums created by the project team. In addition,
+violations of this code outside these spaces may affect a person's ability to
+participate within them.
+
+
+1. **Be friendly and patient**.
+
+2. **Be welcoming**. We strive to be a community that welcomes and supports
+   people of all backgrounds and identities. This includes, but is not limited
+   to, members of any race, ethnicity, culture, national origin, color,
+   immigration status, social and economic class, educational level, sex, sexual
+   orientation, gender identity and expression, age, physical appearance, family
+   status, political belief, technological or professional choices, academic
+   discipline, religion, mental ability, and physical ability.
+
+3. **Be considerate**. Your work will be used by other people, and you in turn
+   will depend on the work of others. Any decision you take will affect users
+   and colleagues, and you should take those consequences into account when
+   making decisions. Remember that we're a world-wide community. You may be
+   communicating with someone with a different primary language or cultural
+   background. For example some miscommunications might happen simply because
+   of these cultural or language differences, not because there is an actual
+   difference of opinion.
+
+4. **Be respectful**. Not all of us will agree all the time, but disagreement is
+   no excuse for poor behavior or poor manners. We might all experience some
+   frustration now and then, but we cannot allow that frustration to turn into a
+   personal attack. It’s important to remember that a community where people
+   feel uncomfortable or threatened is not a productive one.
+
+5. **Be careful in the words that you choose**. Be kind to others. Do not insult
+   or put down other community members. Harassment and other exclusionary
+   behavior are not acceptable. This includes, but is not limited to:
+   * Violent threats or violent language directed against another person
+   * Discriminatory jokes and language
+   * Posting sexually explicit or violent material
+   * Posting (or threatening to post) other people's personally identifying
+     information ("doxing")
+   * Personal insults, especially those using racist or sexist terms
+   * Unwelcome sexual attention
+   * Advocating for, or encouraging, any of the above behavior
+   * Repeated harassment of others. In general, if someone asks you to stop,
+     then stop
+
+6. **Moderate your expectations**. Please respect that community members choose
+   how they spend their time in the project. A thoughtful question about your
+   expectations is preferable to demands for another person's time.
+
+7. **When we disagree, try to understand why**. Disagreements, both social and
+   technical, happen all the time and scikit-optimize is no exception.  Try to
+   understand where others are coming from, as seeing a question from their
+   viewpoint may help find a new path forward.  And don’t forget that it is
+   human to err: blaming each other doesn’t get us anywhere, while we can learn
+   from mistakes to find better solutions.
+
+8. **A simple apology can go a long way**. It can often de-escalate a situation,
+   and telling someone that you are sorry is an act of empathy that doesn’t
+   automatically imply an admission of guilt.
+
+
+This code of conduct is based on [the Jupyter team COC](https://github.com/jupyter/governance/blob/4345f740ed98c7aa578a9482fa36cf5de663ab54/conduct/code_of_conduct.md) as well as [http://todogroup.org/opencodeofconduct/](http://todogroup.org/opencodeofconduct/).
