+# Contributor Covenant Code of Conduct
+
+**Compiler Explorer** contributor covenant Code of Conduct.
+
+## Our Pledge
+
+In the interest of fostering an open and welcoming environment, we as
+ contributors and maintainers pledge to making participation in our project
+ and our community a harassment-free experience for everyone, regardless of age,
+ body size, disability, ethnicity, gender identity and expression,
+ level of experience, nationality, personal appearance, race, religion,
+ or sexual identity and orientation.
+
+## Our Standards
+
+Examples of behavior that contributes to creating a positive environment include:
+
+* Using welcoming and inclusive language.
+* Being respectful of differing viewpoints and experiences.
+* Gracefully accepting constructive criticism.
+* Focusing on what is best for the community.
+* Showing empathy towards other community members.
+
+Examples of **unacceptable** behavior by participants include:
+
+* The use of sexualized language or imagery and unwelcome sexual attention or
+ advances.
+* Trolling, insulting/derogatory comments, and personal or political attacks.
+* Public or private harassment.
+* Publishing others' private information, such as a physical or electronic
+ address, without explicit permission.
+* Other conduct which could reasonably be considered inappropriate in a
+ professional setting.
+
+## Our Responsibilities
+
+Project maintainers are responsible for clarifying the standards of acceptable
+ behavior and are expected to take appropriate and fair corrective action in
+ response to any instances of unacceptable behavior.
+
+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.
+
+## Scope
+
+This Code of Conduct applies both within project spaces and in public spaces
+ when an individual is representing the project or its community. Examples of
+ representing a project or community include using an official project e-mail
+ address, posting via an official social media account, or acting as
+ an appointed representative at an online or offline event.
+ Representation of a project may be further defined and clarified by project
+ maintainers.
+
+## Enforcement
+
+Instances of abusive, harassing, or otherwise unacceptable behavior may be
+ reported by contacting the project owner at
+ [matt@godbolt.org](mailto:matt@godbolt.org). The project team will review
+ and investigate all complaints, and will respond in a way that it deems
+ appropriate to the circumstances. The project team is obligated to maintain
+ confidentiality with regard to the reporter of an incident. Further details of
+ specific enforcement policies may be posted separately.
+
+Project maintainers who do not follow or enforce the Code of Conduct in good
+ faith may face temporary or permanent repercussions as determined by other
+ members of the project's leadership.
+
+## Attribution
+
+This Code of Conduct is adapted from the [Contributor Covenant][homepage],
+ version 1.4, available at [contributor-covenant.org/version/1/4][version]
