+# Code of Conduct
+
+Contact: a moderator ([see below](#moderators)), or a member of the WPT
+community that you feel you can trust.
+
+## 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, sexual identity and
+orientation, or any other dimension of diversity.
+
+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 for our
+community include:
+
+* Demonstrating empathy and kindness toward other people
+* Being respectful of differing opinions, viewpoints, and experiences
+* Giving and gracefully accepting constructive feedback
+* Accepting responsibility and apologizing to those affected by our mistakes,
+  and learning from the experience
+* Focusing on what is best not just for us as individuals, but for the
+  overall community
+
+Examples of unacceptable behavior include:
+
+* The use of sexualized 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
+
+Moderators 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.
+
+Moderators 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, and will communicate reasons for moderation
+decisions when appropriate.
+
+Moderators are held to a higher standard than other community members. If a
+moderator creates an inappropriate situation, they should expect less leeway
+than others.
+
+## Scope
+
+This Code of Conduct applies within all community spaces, and also applies when
+an individual is officially representing the community in public spaces.
+Examples of representing our community include official IRC channels (#testing
+on irc.w3.org); GitHub repositories under the web-platform-tests organization;
+and the [email protected] mailing list.
+
+There may arise situations where both the WPT code of conduct and that of
+another organization (such as the WHATWG or W3C) may apply.
+For example, a WPT-focused meeting at
+[TPAC](https://www.w3.org/2002/09/TPOverview.html) would involve both the WPT
+code of conduct and the [W3C code of ethics and professional
+conduct](https://www.w3.org/Consortium/cepc/).
+In such situations we operate under all code of conducts involved.
+If you are placed in a situation where you feel this is inappropriate (e.g. if
+you believe the code of conducts involved contradict one another), please
+contact a [moderator](#moderators).
+
+## Enforcement
+
+Instances of abusive, harassing, or otherwise unacceptable behavior may be
+reported to the [moderators](#moderators).
+All complaints will be reviewed and investigated promptly and fairly.
+
+All moderators are obligated to respect the privacy and security of the
+reporter of any incident.
+
+Moderators will recuse themselves if they are directly involved in a report of
+a code of conduct violation.
+
+## Enforcement Guidelines
+
+Moderators will follow these Community Impact Guidelines in determining
+the consequences for any action they deem in violation of this Code of Conduct.
+These are not a consecutive set of steps; a single incident may be sufficient
+enough to proceed straight to a temporary ban, for example.
+
+### 1. Warning
+
+**Community Impact**: A violation through a single incident or series
+of actions.
+
+**Consequence**: A warning with consequences for continued behavior, providing
+clarity around the nature of the violation and an explanation of why the
+behavior was inappropriate. A public apology may be requested.
+
+### 2. Temporary Ban
+
+**Community Impact**: A serious violation of community standards, including
+sustained inappropriate behavior.
+
+**Consequence**: A temporary ban from any sort of interaction or public
+communication with the community for a specified period of time. No public or
+private interaction with the people involved, including unsolicited interaction
+with those enforcing the Code of Conduct, is allowed during this period.
+Violating these terms may lead to a permanent ban.
+
+### 3. Permanent Ban
+
+**Community Impact**: Demonstrating a pattern of violation of community
+standards, including sustained inappropriate behavior,  harassment of an
+individual, or aggression toward or disparagement of classes of individuals.
+
+**Consequence**: A permanent ban from any sort of public interaction within
+the community.
