+# Contributor Covenant Code of Conduct
+
+## Our Pledge
+
+We as members, contributors, and leaders pledge to make participation in our
+community a harassment-free experience for everyone, regardless of age, body
+size, visible or invisible disability, ethnicity, sex characteristics, gender
+identity and expression, level of experience, education, socio-economic status,
+nationality, personal appearance, race, religion, or sexual identity
+and orientation.
+
+We pledge to act and interact in ways that contribute to an open, welcoming,
+diverse, inclusive, and healthy community.
+
+## Our Standards

+Examples of behavior that contributes to a positive environment:
+
+* Demonstrating empathy and kindness
+* Being respectful of differing opinions and experiences
+* Giving and gracefully accepting constructive feedback
+* Accepting responsibility and apologizing for mistakes
+* Focusing on what is best for the community
+
+Examples of unacceptable behavior:
+
+* Trolling, insulting or derogatory comments
+* Public or private harassment
+* Publishing others' private information without permission
+* Other conduct which could reasonably be considered inappropriate
+
+## Enforcement Responsibilities
+
+Community leaders are responsible for clarifying and enforcing our standards of
+acceptable behavior and will take appropriate and fair corrective action in
+response to any behavior that they deem inappropriate, threatening, offensive,
+or harmful.
+
+## Scope
+
+This Code of Conduct applies within all community spaces, and also applies when
+an individual is officially representing the community in public spaces.
+
+## Enforcement
+
+Instances of abusive, harassing, or otherwise unacceptable behavior may be
