+# Code of Conduct
+To be a truly great community, Swift.org needs to welcome developers from all walks of life,
+with different backgrounds, and with a wide range of experience. A diverse and friendly
+community will have more great ideas, more unique perspectives, and produce more great 
+code. We will work diligently to make the Swift community welcoming to everyone.
+
+To give clarity of what is expected of our members, Swift.org has adopted the code of conduct 
+defined by [contributor-covenant.org](https://www.contributor-covenant.org). This document is used across many open source 
+communities, and we think it articulates our values well. The full text is copied below:
+
+### Contributor Code of Conduct v1.3
+As contributors and maintainers of this project, and in the interest of fostering an open and 
+welcoming community, we pledge to respect all people who contribute through reporting 
+issues, posting feature requests, updating documentation, submitting pull requests or patches, 
+and other activities.
+
+We are committed to making participation in this project a harassment-free experience for 
+everyone, regardless of level of experience, gender, gender identity and expression, sexual 
+orientation, disability, personal appearance, body size, race, ethnicity, age, religion, or 
+nationality.
+
+Examples of unacceptable behavior by participants include:
+- The use of sexualized language or imagery
+- Personal attacks
+- Trolling or insulting/derogatory comments
+- Public or private harassment
+- Publishing other’s private information, such as physical or electronic addresses, without explicit permission
+- Other unethical or unprofessional conduct
+
+Project maintainers have the right and responsibility to remove, edit, or reject comments, 
+commits, code, wiki edits, issues, and other contributions that are not aligned to this Code of 
+Conduct, or to ban temporarily or permanently any contributor for other behaviors that they 
+deem inappropriate, threatening, offensive, or harmful.
+
+By adopting this Code of Conduct, project maintainers commit themselves to fairly and 
+consistently applying these principles to every aspect of managing this project. Project 
+maintainers who do not follow or enforce the Code of Conduct may be permanently removed 
+from the project team.
+
+This code of conduct applies both within project spaces and in public spaces when an 
+individual is representing the project or its community.
+
+Instances of abusive, harassing, or otherwise unacceptable behavior may be reported by 
+contacting a project maintainer at [[email protected]](mailto:[email protected]). All complaints will be reviewed and 
+investigated and will result in a response that is deemed necessary and appropriate to the 
+circumstances. Maintainers are obligated to maintain confidentiality with regard to the reporter 
+of an incident.
+
+*This policy is adapted from the Contributor Code of Conduct [version 1.3.0](http://contributor-covenant.org/version/1/3/0/).*
+
+### Reporting
+A working group of community members is committed to promptly addressing any [reported 
+issues](mailto:[email protected]). Working group members are volunteers appointed by the project lead, with a 
+preference for individuals with varied backgrounds and perspectives. Membership is expected 
+to change regularly, and may grow or shrink.
