+# Code of Conduct
+
+## Our pledge
+
+We as members, contributors, and maintainers pledge to make participation in the
+Webisters 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.
+
+## Our standards
+
+Examples of behaviour that contributes to a positive environment:
+
+- Demonstrating empathy and kindness toward other people
+- Being respectful of differing opinions, viewpoints, and experiences
+- Giving and gracefully accepting constructive feedback
+- Accepting responsibility, apologising to those affected by our mistakes, and
+  learning from the experience
+- Focusing on what is best for the community
+
+Examples of unacceptable behaviour:
+
+- Sexualised language or imagery, and sexual attention or advances of any kind
+- Trolling, insulting or derogatory comments, and personal or political attacks
+- Public or private harassment
+- Publishing others' private information, such as a physical or email address,
+  without their explicit permission
+- Other conduct which could reasonably be considered inappropriate in a professional
+  setting
+
+## Enforcement responsibilities
+
+Maintainers are responsible for clarifying and enforcing these standards and will
+take appropriate and fair corrective action in response to any behaviour they deem
+inappropriate, threatening, offensive, or harmful. Maintainers may remove, edit, or
+reject comments, commits, code, issues, and other contributions that are not aligned
+with this Code of Conduct.
+
+## Scope
+
+This Code of Conduct applies within all community spaces (repositories, issues, pull
+requests, discussions) and also when an individual is officially representing the
+community in public spaces.
+
+## Enforcement
+
+Instances of abusive, harassing, or otherwise unacceptable behaviour may be reported
+to the maintainers at `thewebisters@gmail.com`. All complaints will be reviewed and
+investigated promptly and fairly. Maintainers are obligated to respect the privacy
+and security of the reporter of any incident.
+
+## Attribution
